Actually, glycolysis takes place in the cytoplasm of the cell, not the mitochondria. Glucose is broken down into pyruvate during glycolysis, and the pyruvate can then enter the mitochondria for further processing in the citric acid cycle and oxidative phosphorylation.

Does glucose enter cells through cell membrane or mitochondria?
Glucose is diffused through facilitated diffusion in the cell membrane. It is oxidised by glycolysis in the cytoplasm and then the products either go through the mitochondria if oxygen is present or goes through fermentation in the cytosoplasm if no oxygen.
Where is pryuvate made in the cell?
Pyruvate is produced in the cell's cytoplasm during the process of glycolysis. Glycolysis breaks down glucose into pyruvate, which can then enter the mitochondria to undergo further energy production in the form of ATP through the citric acid cycle and oxidative phosphorylation.
When does Calvin cycle begin?
When acetyl CoA and oxaloacetate is present.
Do pyruvate molecule which is the product of glycolysis enters the mitrochondria during cellular respiration?
Yes, pyruvate molecules produced during glycolysis enter the mitochondria where they undergo further chemical reactions in the citric acid cycle to generate energy in the form of ATP. This process occurs in the matrix of the mitochondria.
Which of the following would not be usable by the mitochondria in absence of glycolytic enzymes?
Lactate would not be usable by the mitochondria in the absence of glycolytic enzymes. Glycolytic enzymes are necessary to convert glucose into pyruvate, which can then enter the mitochondria for further energy production. Without these enzymes, lactate would accumulate and cannot be metabolized by the mitochondria.

Why only glucose enters into glycolysis why not other sugars directly enter into glycolysis?
Glucose is the preferred substrate for glycolysis because it is the most abundant sugar in the body and can be easily broken down to generate energy. Other sugars need to be converted into glucose or intermediates that can enter the glycolytic pathway before they can be utilized for energy production through glycolysis.
What is the result of glycolysis?
Glycolysis starting with glucose results in the production of 2 x pyruvic acids per glucose which continue on in to the mitochondria, in the presence of oxygen, for complete breakdown; a net gain of 2 x ATP and the production of 2 x NADH2 which can enter the mitochondria and via their donated electrons give rise to 3 x ATP per NADH2 inn the presence of oxygen.
Where is pryuvate made in the cell?
Pyruvate is produced in the cell's cytoplasm during the process of glycolysis. Glycolysis breaks down glucose into pyruvate, which can then enter the mitochondria to undergo further energy production in the form of ATP through the citric acid cycle and oxidative phosphorylation.
What gets reduced in glycolysis?
In glycolisis six-carbon sugar glucose are oxidized into two three-carbon compounds with the production of a small amount of adenosine triphosphate (ATP). Glycolysis has two basic functions in the cell. First, it metabolizes simple six-carbon sugars to smaller three-carbon compounds that are then either fully metabolized by the mitochondria to produce carbon dioxide and a large amount of ATP or used for the synthesis of fat for storage. Second, glycolysis functions to producea small amount of ATP, which is essential for some cells solely dependent on that pathway for the generation of energy.
What happens glycolysis?
The pyruvates enter the mitochondria to further undergo cellular respiration. The ATP molecules are used by the cell.
When does Calvin cycle begin?
When acetyl CoA and oxaloacetate is present.
Which is NOT a pathway in the oxidation of glucose?
Glycolysis is NOT a pathway in the oxidation of glucose. Glycolysis is actually the first step in the breakdown of glucose and serves to produce pyruvate, which can then enter either the aerobic citric acid cycle or anaerobic fermentation pathways for further oxidation.
What chemical enters the mitochondria to continue respiration?
The main chemical that enters the mitochondria to continue respiration is pyruvate, which is produced during glycolysis in the cytoplasm. Pyruvate is then converted into acetyl-CoA before entering the citric acid cycle (Krebs cycle) in the mitochondria to produce energy in the form of ATP through oxidative phosphorylation.
Do pyruvate molecule which is the product of glycolysis enters the mitrochondria during cellular respiration?
Yes, pyruvate molecules produced during glycolysis enter the mitochondria where they undergo further chemical reactions in the citric acid cycle to generate energy in the form of ATP. This process occurs in the matrix of the mitochondria.
Which of the following would not be usable by the mitochondria in absence of glycolytic enzymes?
Lactate would not be usable by the mitochondria in the absence of glycolytic enzymes. Glycolytic enzymes are necessary to convert glucose into pyruvate, which can then enter the mitochondria for further energy production. Without these enzymes, lactate would accumulate and cannot be metabolized by the mitochondria.
The anaerobic phase of respiration occurs primarily in mitochondria?
The anaerobic phase of respiration actually occurs in the cytoplasm outside of the mitochondria. This phase involves glycolysis, where glucose is broken down into pyruvate to generate ATP in the absence of oxygen. The pyruvate can then enter the mitochondria for further processing in the aerobic phase of respiration if oxygen is available.
