Which of following is true about all of the dehydrogenase enzymes that participate in the citric acid cycle? a. they catalyze condensation reactions b. they generate co2 c. they convert a single bond to a double bond d. they generate reduced electron carriers e. they all consumer atp

The correct answer is D.

Explanation:

The Krebs cycle also called the citric acid cycle, is a metabolic pathway marked by a succession of chemical reactions, which is part of cellular respiration in all aerobic cells, where energy is released through the oxidation of acetyl-CoA derived from carbohydrates, lipids and proteins in carbon dioxide and chemical energy in the form of ATP.

The two acetyl-CoA carbons are oxidized to CO2, and the accumulated energy is released in the form of chemical energy: GTP, NADH, and FADH2. NADH and FADH2 are coenzymes capable of accumulating energy in the form of reducing power for conversion into chemical energy. The FADH2 of succinate dehydrogenase characterizes the electron transport chain.

Have a nice day!

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

oh it is true if thats what you are asking
