Question

Most of the reactions of glycolysis require presence of,
(a) Mg⁺⁺ ions
(b) Mn⁺⁺ ions
(c) Ca⁺⁺ ions
(d) K⁺ ions

Answer 1

Answer:mg++ ions

Explanation:

Answer 2

Answer:

Most of the reactions of glycolysis require the presence of (a) $Mg^{++}$ ions.

One molecule of glucose is broken down into two molecules of pyruvate, two hydrogen ions, and two molecules of water during the process of glycolysis. The "high energy" intermediary molecules of ATP and NADH are created during this process. Next, pyruvate molecules engage in the link reaction to create acetyl-coA. The TCA cycle is the next step for acetyl-coA.

One could think of glycolysis as a two-step process. First, energy is used to create intermediates with high energy content; later, during the second stage, these intermediates release their energy.

Two ATP molecules are needed during the energy investment step to create high-energy intermediates.

Energy payout phase: The intermediate is broken down, resulting in the production of two NADH molecules and four ATP molecules.
