Answers

ATP has the energy to _____, while ADP has the capacity

to _____ energy. - ANSWER-Donate, Accept




Chemotrophs can be subdivided into what two additional

subgroups? - ANSWER-The two additional subgroups the

chemotrophs can be subdivided into organotrophs and

lithotrophs.




Chemotrophs, which acquire energy from preformed

chemicals found in the environment, can be divided into

either organotrophs (removing electrons from organic

molecules such as glucose) or lithotrophs, which remove

electrons from inorganic molecules.




Chemotrophs utilize form of phosphorylation? - ANSWER-

The form of phosphorylation that chemotrophs utilize is

oxidative.




Chemotrophs use oxidative phosphorylation (may also

accept substrate level phosphorylation). Oxidative

phosphorylation utilizes the energy released by the

chemical oxidation of nutrients to reform ATP.




What are the three distinct stages in the catabolism of

glucose? - ANSWER-The three distinct stages in the

catabolism of glucose are glycolysis, tricarboxylic acid

cycle, and oxidative phosphorylation.




Glycolysis is the first step of this process and yields 2

molecules of ATP. Next, by either fermentation (or

respiration) 2 additional molecules of ATP can be

produced. Last, the electron transport chain (ETC)

produces 34 ATP via an oxidative phosphorylation event at

the mitochondrial membrane.




What are the reactants of glycolysis? - ANSWER-The

reactant of glycolysis is glucose.
