Adenosine triphosphate

The main energy carrying molecule in cells.(No abbreviations)

Aerobic respiration

Uses oxygen to release energy from carbohydrates and sequester it into ATP.

Anaerobic respiration

Release of energy from carbohydrates without the use of oxygen.

Glycolysis

Process by which glucose is broken down into two pyruvate molecules.

Aerobic respiration

Form of respiration which produces the most ATP for each glucose molecule used.

36

The number of ATP molecules produced by aerobic respiration.

2

The net number of ATP molecules produced by anaerobic respiration.

Oxidation

The removal of electrons from an atom.

Reduction

The addition of electrons to an atom.

Fructose-1,6-bisphosphate

Name of molecule which results from phosphorylation of Fructose-6 phosphate by Phosphofructokinase-1.

Nicotinamide adenine dinucleotide

This is what NAD stands for.

B vitamins

NAD is derived from these vitamins which are not synthesized by vertebrates.

Dihydroxyacetone phosphate

Glycolysis produces this molecule which can be converted to Glyceraldehyde-3-phosphate by the Gly-5 enzyme.

Pyruvate

Glycolysis ends with the formation of two of these molecules.

This molecule is converted into pyruvate.

ATP

This molecule is produced along with pyruvate when the Gly-10 enzyme de-phosphorylates phosphoenolpyruvate.

ATP

This molecule is produced along with 3-phosphoglycerate when the Gly-7 enzyme de-phosphorylates 1,3-bisphosphoglycerate.

4

This is the total number of ATP molecules produced in glycolysis.

2

This is the total number of ATP molecules used in glycolysis.

Lactate fermentation

Muscle cells use this form of respiration when glucose stores are low.

Alcoholic fermentation

Yeast are one organism that utilize this form of anaerobic respiration.

Cristae

This is the name of the folds of the inner mitochondrial membrane.

Cytoplasm

Name of the location where glycolysis is performed.

ATP synthase

This protein is driven by an electrochemical gradient of proteins to drive ATP production in mitochondria.
