Normally glucose is converted to two pyruvate molecules which are then oxidized in the Krebs cycle. Since oxygen is required for this step the pyruvate accumulates and is converted to lactate. In the body lactate is can be converted to glucose in the liver and in some other tissues.
What happens is that pyruvate can accept these Hs. By accepting these Hs, pyruvate becomes Lactic Acid and the co-enzymes are freed to return to glycolysis to pick up more hydrogen's, glucose continues to provide energy anaerobically
What else can I help you with?
What needs to be added to make glycolysis happen?
Glycolysis requires glucose, enzymes, and ATP to occur. Glucose is the starting molecule that is broken down, enzymes facilitate the chemical reactions involved in glycolysis, and ATP provides the necessary energy for these reactions.
How much molecular oxygen is required in the fermentation of one molecule of glucose?
In the fermentation of one molecule of glucose, no molecular oxygen is required. Fermentation is an anaerobic process that does not involve oxygen and is used by some organisms to generate energy from glucose in the absence of oxygen.
Which stages of cellular respiration occur in organisms that go through anaerobic respiration?
In organisms that undergo anaerobic respiration, glycolysis occurs, which does not require oxygen. After glycolysis, fermentation takes place to regenerate NAD+ for glycolysis to continue in the absence of oxygen. The citric acid cycle and oxidative phosphorylation, which require oxygen, do not occur in anaerobic respiration.
When can the Krebs cycle not occur?
when oxygen is not present
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.
Is oxygen necessary for glycolysis?
No - glycolysis is anaerobic (it does occur in the presence of oxygen).
A process that does not need oxygen to be present?
Glycolysis
What happened when no oxygen is present after glycolysis?
fermentation
What happens when oxygen is present after glycolysis?
fermentation
In presence of oxygen glycolysis is followed by?
When oxygen is present, the Krebs Cycle and then the Electron transport chain follow glycolysis. When oxygen is not present, a different pathway follows glycolysis. The combination of glycolysis and the different pathway is called fermentation.
Is glycolysis a aerobic process?
No. Glycolysis is anaerobic and do not require oxygen.
Which of the following normally occurs whether or not oxygen is present?
Glycolysis is a metabolic process that normally occurs whether or not oxygen is present. It is the first step in cellular respiration and involves the breakdown of glucose to produce energy in the form of ATP.
Which stage of respiration occurs whether or not oxygen is present?
Glycolysis literally means "splitting sugars." Glucose, a six carbon sugar, is split into two molecules of a three carbon sugar. In the process, two molecules of ATP and two "high energy" electron carrying molecules are produced. Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of cellular respiration. Without oxygen, glycolysis allows cells to make small amounts of ATP. This process is called fermentation.
Which process in eukaryotic cells will proceed normally whether oxygen (O2) is present or absen?
Glycolysis is a process in eukaryotic cells that will proceed normally whether oxygen is present or absent. Glycolysis breaks down glucose to produce ATP, the cell's energy currency, and occurs in the cytoplasm. It does not require oxygen and is the first step in both aerobic and anaerobic respiration pathways.
What needs to be added to make glycolysis happen?
Glycolysis requires glucose, enzymes, and ATP to occur. Glucose is the starting molecule that is broken down, enzymes facilitate the chemical reactions involved in glycolysis, and ATP provides the necessary energy for these reactions.
