Question

Kreb cycle short note in short points

Answer 1

kreb cycle is a stage of tissue respiration: a series of biochemical reactions occurring in mitochondria in the presence of oxygen by which acetate, derived from the breakdown of foodstuffs, is converted to carbon dioxide and water, with the release of energy. Also called: citric acid cycle, tricarboxylic acid cycle.

Answer 2

$\color{blue}\huge\star\underline\mathfrak{Answer}\star$

The Krebs Cycle, also called the citric acid cycle, is the second major step in oxidative phosphorylation. After glycolysis breaks glucose into smaller 3-carbon molecules, the Krebs cycle transfers the energy from these molecules to electron carriers, which will be used in the electron transport chain to produce ATP.
