What chemical enters the mitochondria to continue respiration?
In aerobic respiration of glucose in eukaryotes, two molecules of pyruvic acid is produced in the cytoplasm by glycolysis of one molecule of glucose. The pyruvic acid then enters the mitochondria to go through the Krebs cycle, which will break down the pyruvic acid into carbon dioxide, which is then excreted. Putting a molecule of pyruvic acid through the Krebs cycle yields 1 molecule of ATP (2 ATP per glucose), but importing the pyruvic acid into the mitochondria costs 1 ATP molecule, so the net gain of ATP from the Krebs cycle is +0. Hydrogen ions and high-energy electrons from glycolysis also need to be imported into the mitochondria to the electron transport chain, which is where the mother-lode of ATP comes from (34 ATP per glucose molecule). Other molecules such as fatty acids and amino acids typically don't undergo glycolysis, but instead are imported directly into the mitochondria where they enter the Krebs cycle somewhere depending on their molecular structure.
Is Pyruvate is a product of glycolysis?
Yes. Pyruvate is a product of glycolysis. This molecule contains three carbons. For every molecule of glucose that enters the glycolytic pathway, two molecules of pyruvate are formed
Can pyruvic acid use in the Krebs cycle?
The pyruvic acid that is produced by glycolysis is used as the initial input for the Krebs Cycle (also called citric acid cycle). In the initial step of the Krebs Cycle, the pyruvic acid is converted to acetyl-CoA via pyruvate decarboxylation. This continues a series of chemical reactions leading to the production of 2 ATP molecules.
How many ATP molecules are produced by oxidative phosphorylation for each glucose that enters glycolysis?
there are 2.5 ATP produced
How is glucose broken down in the mitochondria?
Glucose enters the cell by the glucose transporters. It is then broken down to make ATP in two pathways. Anaerobic metabolism is when oxygen is not required. This is also known as glycolysis which takes place in the cytoplasm.
What does glycolysis produces?
Glycolysis (glycos, sugar + lysis, splitting) A glucose molecule is broken down into two molecules of pyruvic acid. The pyruvic acid molecules are then absorbed by the mitochondria. In the mitochondrial matrix, a CO2 molecule is removed from each of the acid molecules. What is left of the pyruvic acid then enters the Krebs cycle.
What molecules both enters AND exits the Kreb's cycle?
Pyruvic acid enters and carbon dioxide exits.
Is this true or false The pyruvic acid produced in electrolysis enters the chloroplasts if the oxygen is present in a cell?
It is false that if oxygen is present in a cell, pyruvic acid in glycolysis enters the chloroplasts. The pyruvic acid enters the mitochondria if oxygen is present in a cell.

Pyruvic acid loses a molecule of BLANK to produce acetic acid which then enters the citric acid cycle?
CO2 (Carbon Dioxide)

When does Calvin cycle begin?
When acetyl CoA and oxaloacetate is present.
What molecule produced during the breakdown of glucose enters the Krebs cycle?
acetyl CoA
Does pyruvic acid enters the krebs cycle?
Pyruvic acid cycle does enter the Krebs cycle and is turned into acetyl coenzyme A.
How many ATP molecules are produced by oxidative phosphorylation for each glucose that enters glycolysis?
there are 2.5 ATP produced
What purpose does pyruvic acid serve?
Pyruvic acid (or pyruvate) is simply one of the compounds in the metabolic pathway from sugars to carbon dioxide and water. From pyruvate (a three cabon unit) either one of two reactions can occur. It can react to form lactose or lose a carbon dioxide molecule to become a two carbon unit and enter the Krebs cycle.
