What do the the skin, lungs, and digestive system do when drugs enter the system?

Answers

Drugs undergo four stages within the body: absorption, distribution, metabolism, and excretion. Drugs can be absorbed through the skin.
Or, some drugs can be inhaled as gases. Gases penetrate the lining of the esophagus and lungs very quickly, which allows the drug to enter the bloodstream. 
 Once a drug has entered the bloodstream,the blood throughout the body carries the substance with it. 
The digestive system is involved in the process of metabolism of the drugs. and transform drugs into substances that can be expelled by the body. Enzymes within the liver break down the drugs.

In an enzyme controlled reaction, a substrate is the same as

Answers

Final answer:

In enzyme-controlled reactions, a substrate is the reactant or the molecule upon which the enzyme acts. They interact at the enzyme's active site and undergo dynamic changes to facilitate the chemical reaction. Each enzyme is designed to work with a specific substrate.

Explanation:

In an enzyme-controlled reaction, a substrate is essentially the reactant, or the molecule upon which the enzyme acts. The enzyme binds to the substrate at a specific location known as the active site. This binding is facilitated by the unique combination of amino acid side chains within the active site, perfectly suited to bind to one specific chemical substrate (or substrates). Enzymes display specificity because only a substrate with a particular shape and electrical charge can bind to the corresponding active site.

Moreover, enzymes and substrates undergo dynamic changes to induce the transition state of the substrate - a high-energy, unstable state occurring during a chemical reaction. This process known as induced fit, resembles a hand fitting into a glove, where the glove represents the enzyme and the hand represents the substrate.

Therefore, we say that each enzyme is specifically matched for each substrate and hence each chemical reaction. Some enzymes, however, can act on several different but structurally related substrates.

A substrate in an enzyme-controlled reaction is the molecule that the enzyme acts upon. It binds to the enzyme's active site, undergoes a chemical reaction, and is converted into a product. Substrates are crucial for the specificity and the catalytic process of enzymes.

In an enzyme-controlled reaction, a substrate is the molecule that binds to the enzyme's active site. The enzyme catalyzes a chemical reaction, transforming the substrate into a different molecule, known as the product. This process often involves the formation of an enzyme-substrate complex, indicated by the equation E+S
ightarrow ES
ightarrow E+P, where E represents the enzyme, S is the substrate, and P is the product.

Enzymes are highly specific to their substrates due to the unique fit between the substrate and the enzyme's active site, a concept sometimes referred to as the "lock and key" model. However, the induced fit model explains that the active site of the enzyme changes shape upon substrate binding, which facilitates the catalytic process. Substrates play a critical role in biochemical reactions and are not altered or consumed by the reaction, allowing enzymes to be reused multiple times.

The place where an organism lives and that provides the things the organism needs is called its ___________.(7.ec.5b.1) * habitat species community population

Answers

This above description is most suitable to describe an organisms habitat. This is the place that an organism lives and provides the necessities the organism requires.
Final answer:

A habitat is the place where an organism lives and gets the resources it needs. Habitats are part of larger ecosystems, and multiple populations can inhabit the same habitat, forming a community. The collection of all ecosystems is termed the biosphere.

Explanation:

The location or environment where an organism lives is referred to as its habitat. The habitat provides all the essential resources the organism needs, such as food, water, shelter, and the ideal conditions for reproduction. For instance, the forest offers a suitable habitat for pine trees and offers the resources these trees need to grow and reproduce.

A myriad of populations often dwell in the same habitat, forming an ecological community. An example of this can be seen in a forest, which might contain populations of pine trees, flowering plants, insects, and other wildlife. These various populations cohabitating in the forest form its community.

The forest, as a whole, is an ecosystem – an interactive system involving both the organisms (living components) and the abiotic, or nonliving components of the environment like the soil and the rainwater. The habitat is, therefore, a part of this larger ecosystem.

The highest level of biological organization is the biosphere, which is an assemblage of all ecosystems and represents the total inhabited places on Earth. This includes the land, water, and even parts of the atmosphere, essentially all zones where life exists.

Nerve cells send electrical impulses along the _____. when these impulses reach the end of the neuron, they cause a release of neurotransmitters across the _____.

Answers

Nerve cells send electrical impulses along the axon. When these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.
The axon is part of the neuron (nerve cell that carries messages), as well as dendrite. Axons pass the nerve impulses on to other cells, while dendrite receive nerve impulses from other cells. The place where the axon of one neuron meets the dendrite of another is called a synapse.

Answer: Nerve cells send electrical impulses along the axon. when these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.

Explanation:

There are three main parts of neurons:

1) Axon

2) Dendrites

3) Cell body

Axon in a nerve cell send electrical impulses which is known as  action potentials from the nerve cell.

When these impulses reach the end of the neuron , they cause of release of neurotransmitters across the synapse.

Since synapses is the gap between two neurons to allow faster transmission of electrical impulses.

Hence, Nerve cells send electrical impulses along the axon. when these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.

__________ are the raw data of experience, based on the activation of certain receptors located in the various sensory organs.

Answers

The answer is sensations. Sensation alludes to the way toward detecting our condition through touch, taste, sight, sound, and smell. This data is sent to our brains in crude frame where discernment becomes possibly the most important factor. Discernment is the way we decipher these sensations and hence comprehend everything around us.

Final answer:

Sensory receptors are specialized neurons that detect stimuli and start the process of sensory perception, involving reception, transduction, encoding, transmission, and interpretation in the brain. Each type of sensory input has a specific pathway and modality by which it is processed and perceived. This process ensures the conversion of external stimuli into a meaningful experience.

Explanation:

Sensory receptors are the raw data of experience, based on the activation of certain receptors located in the various sensory organs. When a physical or chemical stimulus is detected by a sensory receptor, sensation occurs. The process from a sensory input to a perceived experience involves several steps: reception, transduction, encoding and transmission, and finally, perception.

During the reception phase, sensory receptors are activated by stimuli such as mechanical stimuli, chemicals, or temperature. The transduction phase is where these stimuli are converted into neural signals. Then, through encoding and transmission, these neural signals are processed regarding the type of stimulus, the location, the duration, and the intensity. The sensory information is carried by action potentials along neurons, ensuring that the senses are kept separate as they are transmitted to the brain. Finally, perception occurs in the brain, where the information is interpreted and becomes part of our conscious experience, as depicted in Figure 7.2, which illustrates that sensations and information received by the brain are filtered through emotions and memories to become thoughts.

The main sensory modalities include olfaction (smell), gustation (taste), equilibrium (balance), hearing, and the general senses of somatosensation such as touch, pressure, and pain. Each modality is encoded and transduced in a specific manner unique to the type of sensory input it represents.
