Reorder the following by how many phosphates it has.

• ATP

• AMP

• ADP

Pyruvate dehydrogenase is an enzyme that converts pyruvate to acetyl-CoA. Acetyl-CoA is further metabolized in the Krebs cycle. A researcher measured the accumulation of acetyl-CoA in a reaction containing pyruvate and pyruvate dehydrogenase under several different conditions. Which of the following best describes the cellular location where pyruvate dehydrogenase is most likely active?

• The cytosol

• The lysosomes

• The nucleus

• The mitochondrial matrix

• Synthesis of Acetyl CoA

• Citric Acid Cycle

• Glycolysis

• ETC

• 
• ex - photosynthesis

• Degradative (breaks down) pathway

• anabolic reactions

• 
• ex - amino acids link to form muscle protein

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.

Match the following information to the correct place.

Groups:

(a) Aerobic

,

(b) Anaerobic

• with O2

• Occurs mainly in the mitochondria

• without O2

• makes little ATP

• Release energy from breakdown of food

• • Occurs in the cytosol/cytoplasm

• respiration

• makes lots of ATP

• Keep glycolysis going by regenerating NAD+

• fermentation
