The definition of BMR.
What is the Basal Metabolic Rate, the amount of energy you need just to survive?
500
The reactants of cellular respiration and the products of photosynthesis.
What are oxygen and glucose?
500
The molecule which pyruvate transforms into before joining the Krebs Cycle as citric acid.
What is acetyl CoA?
500
The origin and function of the proton gradient in the mitochondrion.
What is this process? Energized electrons being passed along by the proteins in the electron transport chain provide energy to pump H+ ions (protons) across the cristae. This creates a gradient of size and charge, with a higher concentration of protons in the inter membrane space. The protons "want" to go back down their gradient, but the only way they can is through ATP synthase. As they flow through ATP synthase, they provide it with the energy to convert ADP + P into ATP.
500
Organisms that carry out lactic acid fermentation.
What are bacteria, as well as human muscle cells?
500
Three main sources of ATP in humans.
What is ATP that is stored in your cells, ATP produced by lactic acid fermentation, and ATP produced by cellular respiration?
