AP Biology Energy Review

What does induced fit mean?

• Induced fit is a model describing how enzymes adjust their shape to better fit a substrate upon binding.

• Induced fit refers to the process of enzyme denaturation.

• Induced fit is a term used to describe the static nature of enzyme-substrate complexes.

• Induced fit means that enzymes cannot change shape during the reaction.

Which of the following can affect enzymes? Select all that apply.

• Temperature

• pH

(b) Anaerobic

• Keep glycolysis going by regenerating NAD+

• Release energy from breakdown of food

• fermentation

• without O2

• respiration

• Occurs mainly in the mitochondria

• with O2

• makes little ATP

• • Occurs in the cytosol/cytoplasm

• makes lots of ATP

Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process?

• The high specific heat capacity of water allows the body to absorb a large amount of excess heat energy.

• The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas.

• The high surface tension of water contributes to the physical process by which water leaves the body.

• The high melting temperature of water allows the body to remove excess heat through a phase change of water from solid to liquid.

Which of the following best summarizes the relationship between dehydration reactions and hydrolysis?

• Dehydration reactions eliminate water from lipid membranes, and hydrolysis makes lipid membranes water permeable

• Hydrolysis creates polymers by adding water, and dehydration reactions break down polymers by taking away water

• Dehydration reactions assemble polymers by taking away water, and hydrolysis reactions break down polymers by adding water

• Dehydration reactions ionize water molecules and add hydroxyl groups to polymers; hydrolysis reactions release hydroxyl groups from polymers

According to the endosymbiotic theory, mitochondria and chloroplasts are believed to have evolved through a symbiotic relationship originating when an early ancestor of eukaryotic cells engulfed a prokaryotic cell. Which of the following does NOT represent a piece of evidence to support this theory?

• Mitochondria and chloroplasts contain their own DNA

• Mitochondria and chloroplasts have their own protein synthesis machinery

• Mitochondrial and chloroplast chromosomes are surrounded by a single layer of membrane

• Mitochondria and chloroplasts can self-replicate
