IB Biology 2.8 and 8.2

What is the most common energy currency in living organisms?

• ATP + Pi

• ATP

• ADP

• Pi

What kind of reaction takes place when ATP releases energy?

• Pi

• Condensation

• Anabolic

• Hydrolysis

Which of the following is not a reactant/reagent in cellular respiration?

• C6H12O6

• Energy

• Glucose

• Oxygen

Which of the following happens first in cellular respiration?

• Electron Transport Chain

• Formation of glycogen

• Glycogenolysis

• Glycolysis

Another name for glycolysis is...

• Anaerobic cellular respiration

• Krebs Cycle

• Fermentation

• Aerobic cell respiration

Why are hydrogen/electron carriers important?

• They need energy.

• They get oxidized and reduced

• They help carry electrons and hydrogen to glucose.

• They produce ATP through ETC.

What are the products of glycolysis?

• Two FADH2 molecules

• Two pyruvate molecules

• Two CO2 molecules

• Two Acetyl CoA molecules

Which of the following is true about glycolysis?

• There is no energy produced in glycolysis

• It only creates ATP, does not use ATP.

• There is a net production of ATP and NADH

• It makes the most ATP out of all the parts of cellular respiration

Aerobic cell respiration comprises the following steps...

• Link reaction, Krebs cycle, and ETC

• Cytochrome Q, ATP synthase, Oxidation

• Calvin cycle

• Fermentation, oxidation, and reduction

Why do we need oxygen for cellular respiration?

• Oxygen gets oxidized at the end of cellular respiration to form water

• Because the krebs cycle needs it

• We need oxygen to breathe and it makes ATP

• Oxygen gets reduced at the end of cellular respiration to form water
