Show the math of ATP production/ consumption in glycolysis.

Solutions

Expert Solution

ATP production -

Glycolysis produces 4 ATP molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.

The 4 ATP molecules are produced in the following steps -

a. Conversion of 1,3 bisphosphoglycerate to 3 phosphoglycerate produces 2ATP molecules.

b. Conversion of phosphoenol pyruvate to pyruvate also produces 2ATP molecules.

ATP consumption -

2ATP molecules are consumed in the Glycolysis process. They are used in the following steps. -

a. Conversion of glucose to glucose 6 phosphate

b. Convert of fructose 6 phosphate to fructose 1,6 bisphosphate

ATP produced = 4

ATP consumed = 2

net production = 4 - 2 = 2

The ATP that is generated in glycolysis is produced by substrate-level phosphorylation
ATP synthesis in glycolysis substrate-level phosphorylation The ATP that is generated in glycolysis is produced by substrate-level phosphorylation, a very different mechanism than the one used to produce ATP during oxidative phosphorylation. Phosphorylation reactions involve the addition of a phosphate group to another molecule. Sort the statements into the appropriate bin depending on whether or not they correctly describe some aspect of substrate-level phosphorylation in glycolysis.

During periods of intense activity, when glycolysis is used in the generation of ATP, the reaction lies to the right, decreasing [ADP], generating ATP, and accumulating AMP. However, [ATP] is usually much greater than [ADP], and [ADP] is greater than [AMP]. Determine [AMP] when 7% of the ATP in a hypothetical cell is hydrolyzed to ADP. In this cell, the initial concentration of ATP is 267 μM, and the total adenine nucleotide concentration (the concentration of ATP, ADP, and AMP)...
