An Allosteric Effector is a molecule or other agent that alters enzyme function by changing its shape<span>.</span>
I found the attached image on the internet and it really helps complete this exercise.
First question:
In the presence of an enzyme, the course of the reaction is shown by the
red curve. The necessary energy to make a reaction occur is less when there is an enzyme to help the reaction happen. Enzymes work as catalysts that act over substrates converting them into different molecules in a much accelerated way then it would happen without the enzyme's help, if it would happen at all.
Second question:
The activation energy is represented by
line B. The activation energy is the energy needed to be available for a reaction to happen. If we compare it with line A, which represents the activation energy necessary for a reaction without an enzyme, we can see how much less energy is necessary to dispend when an enzyme is part of the reaction. Line C represents the energy resultant from the reaction.
Answer: Yes.
Explanation:
DNP and cyanide are both cellular respiration inhibitor.
Cyanide is a neurotoxin that can prevent cellular respiration by it's inactivation activity on mitochondria enzymes called cytochrome oxidase.
DNP (2,4-Dinitrophenol is a chemical that inhibit cellular respiration. It help to shuttle proton across cell membranes of living cells by spreading the proton along along the mitochondria and collapsing the force that produced energy for the cell activities.
The blood collection centers eventually refuse to take her blood because the frequency with which she gave blood had left her anemic.
Anemia is a condition that develops when your blood lacks enough healthy red blood cells or hemoglobin.
<span>Therefore her heart must pump more blood to compensate for the lack of oxygen in the blood. The consequences are huge, leading to an enlarged heart or heart failure.</span>
