11. if you used the same experimental design to compare the rates of respiration of a 25 g reptile and a 25 g mammal, at 100 degrees celsius, what results would you expect? explain your reasoning.

Respiration rate will be higher in the mammal than in the reptile.

Explanation:

Warm-blooded animals like mammals have fixed body temperature range any deviation from this range will cause them to utilize more energy in homeostasis and respiration is needeneeded for energy generation. The implication of this is that at higher temperature, the heart rate of mammals will increase and thus respiration also to cause oxygenation of blood.

On the other hand, cold-blooded animals like reptiles cannot and do not maintain homeostasis, thus their body temperature changes with the changing environment. There is no demand on energy to maintain a specific temperature range hence the rate of respiration may not increase.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
