during the first step of glycolysis
C6 is phosphorylated, turning it into a phosphate ester which is a low energy compound.
Glycolysis
Nothing
Glycolysis occurs in the cytoplasm during the first stage of respiration.

Two molecules of ATP are consumed during the first step of glycolysis, where glucose is converted to glucose-6-phosphate by the enzyme hexokinase.
Glucose is first converted to pyruvic acid in a process called glycolysis. During glycolysis, glucose molecules are broken down into two molecules of pyruvic acid, producing a small amount of ATP and NADH as energy intermediates. This process occurs in the cytoplasm of cells and is the first step in both aerobic and anaerobic respiration.
The first step to respiration is glycolysis.
The first reaction in glycolysis is the phosphorylation of glucose to glucose-6-phosphate by the enzyme hexokinase. This step consumes one molecule of ATP to phosphorylate glucose, making it more reactive for subsequent steps in glycolysis.
Glycolysis occurs in the cytoplasm of the cell. It is the first step in cellular respiration and involves the breakdown of glucose into pyruvate, producing ATP and NADH in the process.
During alcohol fermentation, pyruvate, produced from glycolysis, is converted into ethanol and carbon dioxide. This process occurs in anaerobic conditions, where the pyruvate is first decarboxylated to form acetaldehyde, which is then reduced to ethanol by the enzyme alcohol dehydrogenase. This conversion regenerates NAD+, allowing glycolysis to continue and produce ATP in the absence of oxygen.
No
Glucose is broken down into pyruvate.
