After pyruvate is formed, it must either be converted to another molecule to enter the citric acid cycle and ultimately produce ATP by utilizing the electron-transport chain, or go through alternate pathways to produce NAD . Identify the products formed in the pathway of pyruvate and indicate whether NADH H or NAD are produced under aerobic and anaerobic respiration.

hi i’m going crazy about going tomorrow and i’ll tell you what i’m doing and i wanna is a way ya

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
