Kreb>ETC>glycolysis

Where do the carbon atoms in the pyruvic acid end up following the krebs cycle?

The enter ETC and make ATP

The become part of CO that get exhaled

They join with citric acid to make acetyl-CoA

The build up in the intermembrane space

Cell respiration with oxygen is called

Aerobic

Anearobic

Which of the following are produced during the krebs cycle

ATP

NADH

CO2

FADH2

What molecule is the final electron acceptor at the end of the ETC?

Oxygen

CO2

Glucose

NADH

The movement of which ion cross the membrane from the intermembrane space to the matrix causes ATP synthase to spin and make ATP

H+ ions

Na+ ions

Oxygen

Water

Which stage of cellular respiration produces the most ATP

Glycolysis

Krebs cycle

Electron transport

Acetyl-CoA charging

Which of the following happens as electrons pass down th ETC?

Energy from the moving electrons transport H+ ions into the intermembrane space

CO2 is released

Energy from H+ ions crossing back into the matrix causes ATP synthase to make ATP

Water is produced
