Cell Respiration

Question 1

• a process where cells extract energy from food to generate ATP

Answer 1

Cell Respiration

Question 2

• energy molecules responsible for many biological processes and synthesis of other biomolecules

Answer 2

Adenosine triphosphate (ATP)

Question 3

• where ATP is mostly generated

Answer 3

Mitochondria

Question 4

Needed materials for cell respiration to occur

Answer 4

Glucose, Oxygen, Mitochondria

Question 5

Expected products from cell respiration

Answer 5

ATP - 30 to 38 ATP per glucose
Carbon Dioxide - released to the atmosphere, used by autotrophs
Water - will be excreted by the organism

Question 6

• occurs in the cytoplasm of the cell
• Glucose is transformed into Pyruvate since it’s a big molecule. This breaks it down.
• Yields 2 ATP

Answer 6

Glycolysis

Question 7

• occurs in the mitochondria
• Pyruvate will be used to initiate chemical reactions that will generate energy molecules (NADH AND FADH2)
• yields 2 ATP

Answer 7

Krebs Cycle

Question 8

• occurs in the mitochondria
• energy stored in NADH and FADH2 molecules are used to maximize the production of atp
• yields around 32 atp

Answer 8

Electron Transport Chain (ETC) and Chemiosmosis

Question 9

• an alternative way to breakdown glucose and generate ATP when an environment is low on oxygen

Answer 9

Anaerobic Respiration

Question 10

• produced in the muscles during rapid exercise when the body can’t supply enough oxygen to the tissues
• burning sensation in muscles
• occurs in muscle cells

Answer 10

Lactic Acid
