Which of the following best describes the function of the coenzymes NAD and FAD in eukaryotic
cellular respiration?
А
They participate in hydrolysis reactions by
accepting protons from water molecules.
B
They participate directly in the
phosphorylation of ADP to ATP.
с
They serve as final electron acceptors in the
electron transport chain.
D
They aid vitamins such as niacin in the breakdown
of glucose.
E
They accept electrons during oxidation-reduction
reactions

My best answer is c.

Explanation:

They serve as final electron acceptors in the electron transport chain. ... Photosynthesis produces more oxygen than is consumed by respiration during the day.

Im pretty sure its correct lol :)

one comes through sex and the other does not lul im not

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
