Which statement best describes the principle of feedback inhibition in metabolic regulation?Question 20Answera.The initial enzyme in a pathway is inhibited by the accumulation of its substrateb.The end product of a pathway increases enzyme activity at the beginning of the pathwayc.The final product of a pathway inhibits the action of earlier enzymes in the pathwayd.All enzymes in a pathway are inhibited equally by the final product

Which of the following statements about feedback inhibition is false?ANSWERCells use feedback inhibition to manage their production of many biologically important compounds.It is accomplished by an end product acting as either a competitive inhibitor or as an allosteric inhibitor of an enzyme earlier in the pathway.Feedback inhibition is irreversible.Feedback inhibition slows down (or can even turn off) biochemical pathways to help cells be efficient.

Name the inhibition where the end product of the biosynthetic pathway inhibits the activity of the first enzyme.  Competitive inhibition   Feedback repression   Feedback inhibition   Noncompetitive inhibition   Allosteric inhibition

Which of the following statements is true concerning feedback mechanisms? Which of the following statements is true concerning feedback mechanisms? Negative feedback mechanisms work to prevent sudden severe changes within the body. Positive feedback mechanisms always result in excessive damage to the host. Blood glucose levels are regulated by positive feedback mechanisms. Negative feedback mechanisms tend to increase the original stimulus.
