Explanation:

Glycolysis wake up in the cytosol (the liquid containing the organelles) that the cell. The following step in moving respiration, the citric mountain cycle, wake up in the mitochondria.

You are watching: Glycolysis occurs in which part of the cell


Explanation:

Fermentation oxidizes molecules of NADH to NAD+ therefore the cell have the right to have oxidizing agents for any type of subsequent glycolysis reactions. The does not, however, produce any kind of usable energy in the process.

Fermentation leads to the production of ethanol in yeast cells and lactic mountain in muscle cells.


Explanation:

Glycolysis wake up in the cytosol the cells. As soon as finished, the 2 pyruvate products are transported into the mitochondria come go with the citric acid cycle, at a price of 1 ATP every pyruvate. Neither the nucleus, nor the endoplasmic reticulum have actually any role in glycolysis or the citric acid cycle.


Explanation:

The switch of glucose to two pyruvate molecule in glycolysis produces a net full of two direct ATP. When fructose-1,6-bisphosphate enters glycolysis, the bypasses the 2 steps affiliated that normally price one ATP each, therefore, there is no compelled input and the net complete is four created ATP.

We need to remember the each step beyond the conversion of fructose-1,6-bisphosphate come glyceraldehyde-3-phosphate and also dihydroxyacetone phosphate happens twice, or we would come up with two ATP created.

Example question #5 : to move Respiration


Which of the following assets is not created during glycolysis?


Possible Answers:

ATP


Oxygen


Pyruvate


NADH


Correct answer:

Oxygen


Explanation:

Glycolysis is the an initial step in moving respiration, and also is viewed in both aerobic and also anaerobic respiration. The products of glycolysis space pyruvate, NADH, ATP, and water. Oxygen is only a product that the irradiate reactions of photosynthesis; the is consumed as a reactant in the electron move chain.

Example inquiry #6 : cellular Respiration


Which of the complying with processes does no take place during glycolysis?


Possible Answers:

An end an outcome is the production of 3-carbon molecules that are later on fed right into the citric acid cycle


Two

molecules are produced


Via a complex chain the steps,  and  carry electrons come the process"s last electron acceptor,


One molecule that glucose ultimately yields 2 molecules that pyruvate


Four ATP molecules are developed for every molecule that glucose, yet the net manufacturing is just two molecules of ATP


Correct answer:

Via a facility chain of steps,  and  transport electrons come the process"s final electron acceptor,


Explanation:

Glycolysis, which wake up in the cytoplasm, is the an initial step of cellular respiration. Despite it go not develop a large amount of ATP through itself, the incorporates several necessary steps that need to take ar to yield a lot more significant amount that ATP later. Notable events that occur throughout this multi-step procedure include the failure of each glucose molecule into two 3-carbon pyruvate molecules, the manufacturing of 2 molecules that

, and the net manufacturing of 2 ATP molecules.

Unlike the next two steps (the citric acid cycle and also oxidative phosphorylation), glycolysis can happen in the absence of oxygen. The just step offered that is not component of glycolysis is the move of electron from carrier molecules come oxygen via a series of steps. This happens during oxidative phosphorylation and, uneven glycolysis, is one aerobic process.

Example question #7 : cellular Respiration


In comparison come fermentation, the aerobic pathways of glucose metabolism yield more __________.

 


Possible Answers:

acetaldehyde 


pyruvate


ethanol


adenosine triphosphate 


Correct answer:

adenosine triphosphate 


Explanation:

Fermentation is the metabolic procedure that takes location in anaerobic atmospheres to regenerate

*
for glycolysis, i beg your pardon takes ar in both aerobic and anaerobic environments. Since glycolysis is unaffected by the visibility of oxygen, pyruvate concentrations will certainly be the same in one of two people environment. During fermentation the cell changes the pyruvate into acetaldehyde. Ethanol is likewise a product of fermentation. We would certainly not intend to see more acetaldehyde or ethanol in aerobic metabolism.

Adenosine triphosphate (ATP) is the key product of cellular respiration, and the molecular energy of the cell. Aerobic metabolism outcomes in a much higher yield that these power carrying molecules due to the reality that it can use oxygen as a final electron acceptor in the electron transfer chain.

Example concern #1 : cellular Respiration


Where walk glycolysis take place in the cell?


Possible Answers:

Nucleus


Endoplasmic reticulum


Cytosol


Mitochondria


Correct answer:

Cytosol


Explanation:

Glycolysis takes place in the cabinet cytosol, and also can take location under anaerobic conditions. ~ the completion of glycolysis, the product pyruvate is transported to the mitochondria because that the citric acid cycle and also electron transport chain.

The nucleus residences the cell"s DNA, and also the endoplasmic reticulum is connected with protein modification.

Example inquiry #1 : expertise Glycolysis


Which that the complying with stages of moving respiration generates ATP, regardless of the visibility of oxygen?


Possible Answers:

Glycolysis


Oxidative phosphorylation


Krebs cycle


Electron transfer chain


Citric mountain cycle


Correct answer:

Glycolysis


Explanation:

Glycolysis is the process that counter glucose come pyruvate. That produces a complete of four ATP, however consumes 2 ATP, for a net yield of two ATP. Glycolysis is no dependent top top the presence of oxygen and also can happen in one of two people aerobic or anaerobic environments.

The citric mountain cycle, or Krebs cycle, is provided to generate NADH native pyruvate. The NADH is then offered in the electron transfer chain to generate a proton gradient, which fuels oxidative phosphorylation. Due to the fact that oxidative phosphorylation needs an oxygen molecule, the citric mountain cycle and electron move chain cannot continue in anaerobic environments.

Example question #1 : expertise Glycolysis


What is the net manufacturing of ATP native one glucose molecule in glycolysis?


Possible Answers:


*


*


*


Correct answer:


Explanation:

Glycolysis produces four molecules of ATP, but two molecules are offered to finish reactions during the initial actions of the process. With 4 molecules produced and also two molecules consumed in the process, over there is a net yield of two ATP from every glucose molecule in glycolysis

During ATP synthetic in the electron transport chain, approximately 32 extr ATP room generated.
