which of the following statements about glycolysis is

false

• glycolysis has steps involving oxidation-reduction reactions

• the enzymes of glycolysis are located in the cytosol of the cell

• glycolysis can operate in the complete absence of O₂

• the end products of glycolysis are CO₂ and H₂O

• glycolysis makes ATP exclusively through substrate-level phosphorylation

in glycolysis, for each molecule of glucose oxidized to pyruvate

• 2 molecules of ATP are used and 2 are produced

• 2 molecules of ATP are used and 4 are produced

• 4 molecules of ATP are used and 2 are produced

• 2 molecules of ATP are used and 6 are produced

• 6 ‘olecules of ATP are used and 6 are produced

In presence of oxygen, 3- carbon pyruvate can be catabolized in krebs cycle. First however, it loses a carbon, given off as CO₂. Then oxidized to form a 2-carbon compound called acetate, and then is bonded to a coenzyme. These steps result in formation of?

• acetyl CoA, O2, ATP

• acetyl CoA, FADH₂ and CO2

• acetyl CoA, FAD, H+, and CO2

• acetyl CoA, NADH, H⁺ and CO2

• acetyl CoA, NAD+, ATP and CO2
