Most of the cell membrane's specific functions are controlled by: Proteins Alcoholic Fermentation is a form of: Anaerobic Respiration Phagocytosis is a form of: Endocytosis What is a pyruvate? Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. One molecule of glucose breaks down into two molecules of pyruvate, which are the...

BIOLOGY 101 Cell Division Gizmos Student Exploration: Cell Division Vocabulary: cell division, centriole, centromere, chromatid, chromatin, chromosome, cytokinesis, DNA, interphase, mitosis Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Cells reproduce by splitting in half, a process called cell division. What do cells need to do between divisions to make sure that they don’t just get smaller and smaller? In between cell division the cells go through the interphase stag...
