How many energy conversions occur when both acetyl-coa molecules go through the krebs cycle?
a.5
b.6
c.10
d.12

The correct answer would be C.10.

Krebs cycle is a part of cellular respiration that takes place in the mitochondria.

Five energy conversions take place in one complete cycle of the Krebs cycle.

These conversions lead to the formation of three molecules of NADH, one molecule of FADH₂ and one molecule of ATP.

Thus, total 10 energy conversions would occur in two rounds of Krebs cycle or when 2 molecules of acetyl-CoA go through the cycle.

It affects life on Earth by causing the heat rays of the sun weaker.

Explanation:

The ozone layer acts as a shield for life on Earth. The stratospheric ozone layer absorbs ultraviolet (UV) radiation, preventing dangerous UV rays from hitting Earth's surface and harming living organisms.
