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.

∙ 14y agoNAD+ 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

∙ 11y agoNAD 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.

∙ 13y agolike 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.

∙ 12y agoNADH 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.

What is the difference between NAD and NADH?
A NAD is an electron carrier involved in glycolysis and NADH is a hydrogen carrier involved in glycolysis.
How many grams of lactic acid are in a 0.5M solution of lactic acid?
NAD+ is regenerated, allowing glycolysis to continue
Describe the role of fermentation in maintaining ATP and NAD plus levels?
Fermentation allows glycolosis to take place. Glycolysis is a process during which, 2 ATP are used to produce 4 ATP, for a net profit of 2 ATP. When oxygen is not present, fermentation allows Glycolysis to continue by creating 2 ATP which are then used to restart the process of glycolysis. Even though the amount of ATP created is small, the process is still able to continue.
What is the Oxidized form of the most common electron carrier needed in both glycolysis and Krebs cycle?
NAD+ is the oxidized form of the most common electron carrier needed in both glycolysis and the Krebs Cycle.
How does ethanol inhibit glycolysis?
Ethanol (CH3-CH2-OH) is metabolized into an aldehyde (CH3-CHO) via the enzyme alcohol dehydrogenase(ADH). Written out, it looks like this : CH3CH2OH + NAD+ → CH3CHO + NADH + H+ The ADH reaction generates NADH/H+ as one of the products. NADH/H+ is also one of the products of glycolysis (in the glyceraldehyde 3-phosphate dehydrogenase reaction). NADH/H+, being one of the products in glycolysis, also acts as an inhibitor for glycolysis, which is a way of self-regulation for the metabolic pathway.
What is the function of NAD plus glycolysis?
to accept high energy electrons
What is an important example of an electron acceptor that functions in glycolysis?
NAD+ is an important example of an electron acceptor that functions in glycolysis.
What happens when no NAD plus is present during glycolysis?
if NAD+ is not availabe, glycolysis will stop and the cell will DIE
What is the difference between NAD and NADH?
A NAD is an electron carrier involved in glycolysis and NADH is a hydrogen carrier involved in glycolysis.
Can high levels of NADH and low levels of NAD plus stimulate glycolysis?
No it cannot. NADH inhibits glycolysis, the Krebs Cycle and the electron transport chain. HIGH levels of NAD however does stimulate glycolysis but High levels of NADH and low levels of NAD does not stimulate glycolysis but rather inhibits it.
What molecule does fermentation provide to glycolysis?
Pyruvic acid is made during glycolysis and is later used in fermentation.
What energy-carrier molecules are produced by glycolysis?
NADH and ATP
Glycolysis depends on a continuous supply of?
Glucose and NAD+
Glycolysis depends on a continuous supply of what?
glucose and NAD+
Enzymes used in glycolysis?
glucose, fructose, glyceraldehyde
What happens when NAD plus becomes NADH?
Nadh is the reduced form of Nad+. Nad+ acts as a oxidizing agent and can accept electrons in various chemical reactions in the cell.
Why can glycolysis supply energy to cells when oxygen is not avalable?
Glycolysis can occur without oxygen. Although glycolysis does not require oxygen, it does require NAD+. Cells without oxygen available need to regenerate NAD+ from NADH so that in the absence of oxygen, at least some ATP can be made by glycolysis.
