When acetyl-CoA is fed into the TCA cycle, it eventually forms carbon dioxide. The energy released from this oxidation is conserved in the form of (mark all that apply):a. FADH2 b. Water c. GTP d. Protons e. NADH

The correct answer is:

a)FADH2

c)GTP

e)NADH

Explanation:

The Citric acid cycle(TCA) also known as the Kreb cycle, is a focal metabolic center of the cell. It is a sequence of chemical reactions in which the acetyl portion of acetyl CoA is degraded to carbon dioxide and hydrogen atoms.These reactions all occur in the matrix of the mitochondria. This cycle is also an important source of precursor for other molecules such as amino acids, nucleotide bases cholesterol etc. The function of the citric acid cycle is the gathering of high-vitality electrons from carbon fuels. The citric acid cycle removes electrons from acetyl CoA and use it to reduce NAD and FAD into NADH2 and FADH2 respectively.

Overall, The citric acid cycle oxidizes two carbon units(from acetyl CoA) and produces two molecules of carbon dioxide, one molecule of GTP and high energy electrons which are present in the form of NADH2 and FADH2

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
