What is the function of NAD in glycolysis?

Answer 1

NAD+ picks up the electrons that are removed during glycolysis --> makes a molecule of NADH. This NADH goes to the electron transport chain where it gives up the electron to the electron transport chain.

Answer 2

NAD+ is a proton (H+) acceptor and electron (2e-) and becomes NADH ... later on, during the electron transport system/chain and oxidative phophorilation, the H+ is removed from the NADH and goes through a proton pump protein, which gives enough energy to make ATP: you get 3 ATP's per NADH ... the same thing happens with FAD: it's also a proton/e- acceptor but you get 2 ATPs for every FADH ... the electrons are ultimately picked up by oxygen, which is why oxygen is called the terminal electron acceptor

but for products for glycolysis, to get the products you need something pick up protons/electrons from intermediate chemicals so that's what NAD+ and FAD are for: ultimately you get 2 pyruvates and 2 NADHs (I think) from 1 glucose during glycolysis ... then the pyruvate becomes becomes acetyl co-A in an intermediary step that releases CO2 and another NADH per pyruvate : when acetyl co-a goes through the Krebs cycle you get 3 more NADH's and 1 ATP

Answer 3

NAD is a co-enzyme which accepts hydrogen during the metabolic pathway of glycolysis; the particular step involving the reduction of NAD also involves glyceraldehyde phosphate dehydrogenase as the enzyme catalyzing the reaction.

Answer 4

like NADP+ in photosynythesis, each NAD+ accepts a pair of high-energy electrons. This molecule, known as NADH, holds the electrons until they can be transferred to other molecules. By doing this, NAD+ helps to pass energy from glucose to other pathways in the cell.

Answer 5

NAD acts as a coenzyme in glycolysis by accepting hydrogen atoms (protons and electrons) from glucose during the oxidation of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate. This helps to drive the production of ATP in glycolysis. NAD is reduced to NADH during this process, which can then carry the electrons to the electron transport chain for further ATP production.

Answer 6

NADH is a reduced form of NAD (it has gained electrons). It is an electron carrier that takes the electrons to the ETC (electron transport chain) where they are then used to synthesize ATP.

Answer 7

NAD+ picks up the electrons that are removed during glycolysis --> makes a molecule of NADH.

Answer 8

In glycolysis, ultimately, 2 NAD+ is reduced to form 2NADH as a product along with a net product of 2 ATP and 2 pyruvate.

Answer 9

to accept high energy electrons
