Q20:
Q1: Why is it important that enzymes are not permanently altered when they bind with substrate molecules? Q2: How would a higher temperature or higher salt concentration make it more difficult for an enzyme to function effectively? Q3: If a cell was unable to produce a particular enzyme necessary for a metabolic pathway, describe how the absence of that enzyme would affect the cell.

- Q48arrow_forwardSkeletal muscle myosin heavy chain is a mechanoenzyme that requires ATP for its function. Other enzymes, such as phosphofructokinase-2, also rely on ATP. How are PFK-2 and myosin Il different in their use of ATP? • View Available Hint(s) Both enzymes use ATP in the exact same way. PFK-2 functions as a kinase, whereas myosin functions as a phosphatase. PFK-2 catalyzes ATP hydrolysis, whereas myosin does not. Myosin catalyzes ATP hydrolysis, whereas PFK-2 does not. PFK-2 binds to ATP or ADP + Pj, whereas myosin undergoes covalent modification via phosphorylation. Submitarrow_forward• During vigorous exercise, alanine can accumulate in skeletal muscle.
