What critical process would be inhibited?b.A drug is known to inhibit the formation of the cell plate during cytokines is. Would this drug affect human cells? Briefly explain your answer.c. Cancer can be described as loss of control over the cell cycle. Briefly explain how a car losing its brakes is a good analogy to describe the loss of protein checkpoints of the cell cycle? d.Feedback inhibition is a common regulatory mechanism. Describe what feedback inhibition is and explain why it is an efficient system for regulating biochemical pathwayse.To efficiently manage metabolism, cells need to precisely coordinate and regulate a complex web of chemical reactions. Explain why cells need to efficiently manage metabolic pathways and why it is an evolutionary advantage to do so. f.What are the stages of cellular respiration? What does each one do? What does each one produce?
