Chapter 6 Glycolysis

What happens to the pyruvate formed in glycolysis?

it is transported into the mitochondria, and is changed to carbon dioxide. this two carbon compound is then oxidized while NAD+ is reduced to NADH coenzyme A joins the two carbon group to form acetyl coenzyme A, which enters the citric acid cycle

Where does glycolysis take place?

cytosol/cytoplasm

What is glycolysis often called?

the universal energy harvesting process of life

Explain steps 1-4 of glycolysis.

this is the energy investment phase; energy is consumed as two ATP molecules work to energize a glucose molecule, which is then split into two sugars that are primed to release energy

Explain steps 5-9 of glycolysis.

this is the energy payoff phase; two NADH molecules are produced and ATP is generated

What is produced in the intermediate cycle?

2 carbon molecules with acetyl COa 2 NADH 2 Co2

What is produced in glycolysis?

2 molecules of pyruvate, 2 molecules of NAD+, and 2 molecules of ATP

How long has glycolysis had a role in fermentation and respiration?

about 3.5 billion years ago dates back to life long before oxygen, when prokaryotes were life's sole inhabitants

How is ATP formed in glycolysis?

by substrate level phosphorylation, which converts ADP to ATP by the transfer of a phosphate group; ADP has two phosphate groups and when it gains another phosphate molecule generates ATP, NADH, and FADH2

In a summary, what does glycolysis do?

glycolysis enzymatically cuts in half a single molecule of glucose through a series of steps, into two molecules of pyruvate

What is the ancient history of glycolysis supported by?

its occurrence in all domains of life its location within the cell, using pathways that don't involve membrane-bound organelles

Does glycolysis require oxygen?

no, its anaerobic
