How many ATP are produced by the ETC?

A) 2
B) 4
C) 12
D) 32

The electron transport chain or ETC for short has 34 ATP (Adenosine Triphosphate or the energy carrying molecule) Which has the molecular formula C10H12N5O13P3. So I would go with D because this is closest.

This is because one molecule of glucose in a Eukaryotic cell generates around 30 to 32 ATP.

Explanation:

The 34 ATP produced by ETC(Electron transport chain) or the electron transport stage produces the most ATP(energy carrying molecule) out of any stage in aerobic respiration/ cellular respiration cycle. While the krebs cycle, and Glycolysis produce 2 ATP each. Making the rest of the stages 30 ATP total.

in 1972 the fluid—mosaic membrane model of membrane structure was proposed based on thermodynamic principals of organization of membrane lipids and proteins and available evidence of asymmetry and lateral mobility within the membrane matrix [s. j. singer and g. l. nicolson, science 175 (1972) 720–731].

answer; ///(b) it is composed of four protein chains and four heme groups;
