Question

Quizplus · Accepted Answer

Proteins that regulate the cell cycle and fluctuate in concentration are called cyclins. Kinetochores are protein structures on chromosomes involved in cell division, kinases are enzymes that regulate various cellular processes including the cell cycle, ATPases are enzymes that hydrolyze ATP for cellular energy, and proton pumps are membrane proteins that transport protons across cell membranes.
