Glycolysis is the break down of

Lactose

Fructose

Maltose

Glucose

Glycolysis

Takes place in the mitochondria

Produces no ATP

It is same as fermentation

Reduces two molecules of NAD⁺For every glucose molecule processed

When a green plant performs photosynthesis at it maximum rate

The energy content of the plant will be low

The rate of water loss in high

The water content of the plant will be low

The energy content will be unaffected

In the first step of citric acid cycle, acetyl CoA reacts with oxaloacetate to form

NADH

Pyruvate

Citrate

ATP

Co-enzyme Q is in turn oxidized by cytochrome

a²

a

b

a³

When deprived of oxygen, yeast cells obtain energy by fermentation, producing carbon dioxide, ATP, and

Acetyl CoA

Ethyl alcohol

Pyruvate

Lactate

The mechanism for ATP synthesis is

Chemiosmosis

Chemosynthesis

Phosphorylation

Photosynthesis
