BIOL 191 Practice Exam 2

A catabolic reaction involves....?

• the breakdown of complex molecules into simpler ones, releasing energy.
• the conversion of one type of energy into another without any molecular breakdown.
• the transformation of energy into heat without any chemical change.
• the synthesis of simple molecules into complex ones, consuming energy.

What differentiates ATP from ADP?

• ATP has three phosphate groups; ADP has two.
• ATP is produced in the mitochondria; ADP is produced in the nucleus.
• ATP is a nucleotide; ADP is a protein.
• ATP has two phosphate groups; ADP has three.

How does oxidative phosphorylation produce large amounts of ATP

• It produces ATP by breaking down glucose directly.
• ATP is generated through fermentation processes.
• Oxidative phosphorylation occurs in the cytoplasm without a proton gradient.
• By using a proton gradient generated by the electron transport chain to drive ATP synthesis.

When does Fermentation take place?

• Fermentation occurs in aerobic conditions.
• Fermentation happens only in the presence of light.
• Fermentation takes place in anaerobic conditions.
• Fermentation is a process that requires oxygen.

Where does the light independent reaction occur?

• Thylakoid membrane
• Cytoplasm of the cell
• The Mitochondria

• The Stroma

What is the function of the Photosystems?

• To store energy in the form of glucose.
• To absorb carbon dioxide from the atmosphere.
• To release oxygen as a waste product of respiration.
• Capture light energy and transfer it to electrons

Which direction do molecules want to flow?

• Low concentration to high concentration

• High concentration to low concentration
