Answer:
A drug can be described as any chemical which effects the functioning of the body of an organism.
- Certain drugs like nicotine activate the cholinergic receptors. The cholinergic receptors are usually activated by Acetylcholine . When drugs such as nicotine activate the cholinergic receptors, it can influence the normal functioning of the brain.
- Certain drugs such as cocaine might increase the synaptic concentrations of certain neuron transmitters.
- Certain drugs cause the the release of monoamine neurotransmitters such as dopamine, norepinephrine from presynaptic neurons.
- Certain drugs might effect the biochemcial pathway for the transmission of neurons.
<u>Answer:</u>
Enzymes 'reduces the activation energy' of both Exergonic and Endergonic Reaction by acting as a catalyst.
<u>Explanation:</u>
- For example, in the case of 'carbonic anhydrase', enzymes act rapidly causing the chemicals to 'react 107 times faster' than they would normally.
- Enzymes are substrate specific meaning an enzyme working on one substance may not work on another.
- Function of the enzyme is identified by its 'shape of the protein' and arrangement of these molecules produces an area called activation site.
Do u have snap bc there’s a gc where we help each other with work if u need it
Fermentation occurs only when there is not sufficient oxygen available to permit aerobic reactions. (Note, this isn’t pictured in that overall picture at the top of this post).
Let’s pretend your muscles don’t have enough oxygen to attach these “hot potato” hydrogens onto oxygen. The NAD will then reattach these hydrogens back onto the middle carbon of each pyruvate to create lactic acid. The same way pyruvate is known as pyruvic acid, lactate is also called lactic acid, they are the same thing.
