The CORRECT statement about cell respiration is

• Kreb cycle produce oxygen

• Cell respiration requires carbon dioxide

• cell respiration produce 36 ATP molecules

• glycolysis happens in mitochondria

Glycolysis happens in

• nucleus

• cytosol

• mitochondria

• Golgi apparatus

Kreb cycle happens in

• ribosome

• nucleus

• cytosol

• mitochondria

Glucose is broken into 2 chains of pyruvic acid

The above statement refers to

• electron transport chain

• Kreb cycle

• glycolysis

• acetyl co-enzyme A

The CORRECT statement about Kreb cycle is

• breakdown of 1 glucose molecule

• happens in mitochondria

• produce pyruvic acids

• need carbon dioxide

Glycolysis is also known as

• aerobic cellular respiration

Metabolism refers to

• breaking down of large molecules into smaller molecules

• combination of smaller molecules to become large molecules

• chemical reactions that happen in the body

Anabolism refers to

• all chemical reactions that happens in the body
