The point of the Krebs Cycle is to...

• Produce high amounts of ATP using a proton gradient

• Move high energy electrons through series of proteins to eventually bind with O₂, creating water and protons

• Break down pyruvate to produce electron carrier molecules, FADH₂ and NADH, as well as CO₂ and ATP as byproducts

• Use ATP and NADPH to produce 6 carbon sugars

Chemiosmosis is best described as...

• Moving high energy electrons through carrier molecules toward oxygen

• The use of a proton gradient to power ATP Synthase and produce ATP

• The breakdown of pyruvate into electron carrier molecules

• The enzyme that combines ADP and inorganic phosphate to produce ATP

What effect does adding an enzyme to a reaction cause?

• increasing the time it takes for the reaction to occur

• increases the activation energy

• decreases the activation energy

• increasing the amount of energy necessary for the reaction

Enzyme X has an optimum rate of reaction at 97 degrees Fahrenheit. How would rate of reaction be affected if temperature fell to 92 degrees Fahrenheit?

• increase - not as hot

• decrease - no substrate would be produced

• increase - more substrate would be produced

• decrease - cause a change in the shape of the protein
