Cellular Respiration and Photosynthesis

What is the organelle responsible for photosynthesis?

• Mitochondria

• Chloroplast

• Nucleus

• Cytoplasm

The Calvin Cycle uses what things to make glucose:

• ATP

• NADPH

• CO2

• light

The three things plants need are sunlight, water, and CO2 for photosynthesis.

• True
• False

What does the NADH and/or FADH2 that is brought to the electron transport chain come from?

• Glycolysis

• Krebs cycle

• Pyruvate oxidation

• Cytoplasmic reactions

Describe what would happen if the mitochondrial inner membrane was ruptured.

• ATP synthesis would be inhibited

• ATP synthesis would be promoted

• The electron transport chain would increase in activity

• The electron transport chain would decrease in activity

Where does the Krebs cycle take place?

• mitochondrial matrix

• cristae

• cytosol

• chloroplast

What is the starting material for the Krebs cycle?

• glucose

• pyruvate

• acetyl CoA

• G3P

How does the Krebs cycle allow for ATP synthesis?

• The rotation of the Krebs cycle turns a "rotor" in the cell to synthesize ATP

• ATP is synthesized by substrate level phosphorylation during the removal of the coenzyme A upon entrance into the cycle

• Krebs cycle completes the breakdown of glucose to release the energy and store it in the form of ATP

• High energy electrons are stored in NADH and FADH₂ to shuttle to the ETC to generate a proton gradient

Which of the following is NOT a step in cellular respiration?

• Glycolysis

• Krebs Cycle

• Oxidative Phosphorylation

• Calvin Cycle

Where does glycolysis take place?

• Cytosol

• Mitochondrial Matrix

• Mitochondrial Cristae

• Stroma

• Thylakoid Membrane
