According to the graph, enzyme B will function best at what temperature and pH level?
Temperature of 75 and pH of 8
Temperature of 37 and pH of 2
Temperature of 75 and pH of 2
Temperature of 80 and pH of 7
When do enzymes function best?
Under specific temperature and pH levels.
Under perfect atmospheric conditions.
When co-enzymes are present.
In any condition.
Enzymes are specific to a substrate. What happens if an inhibitor attaches to the enzyme?
The enzyme won’t be able to create more enzymes
The substrate will attach itself to the inhibitor
The enzyme will attack the inhibitor
The substrate won’t be able to attach to the enzyme
Enzymes are specific to a substrate and the shape of the enzyme determines the enzyme's function.
True
False
If a person has an infection, the body temperature may increase. Where does the energy come from?
decreasing the rate of cellular respiration.
increasing the rate of cellular respiration in the mitochondria
decreasing the rate of glucose production
increasing the rate of mitosis
Why is energy required for active transport?
The particle is being transported against the concentration gradient.
The particle is water, so it weighs more.
The particle is waste matter that will be digested by the cell membrane.
The distance is greater for this molecule so it requires energy.
If molecules move across the cell membrane to create homeostasis (equilibrium), what will change the most?
the shape of the molecules
the temperature of the molecules
the concentration of the molecules
the pH level of the molecules
