What is cellular metabolism? - ANSWER ✔✔Metabolism is a
controlled set of biochemical reactions that occur in living organisms in
order to maintain life
What is the primary function of enzymes, and how are they regulated? -
ANSWER ✔✔Enzymes speed up chemical reactions. Most notably, the
enzyme is not consumed during the reaction and can be used repeatedly
by the cell. Enzymes can also be regulated by a cofactor such that in the
,absence of the proper cofactor, enzymes are inactive while in its
presence enzymes are active.
What is the difference between catabolism and anabolism? - ANSWER
✔✔Catabolism is the process of breaking down larger molecules into
useful energy sources whereas anabolism is the building up or
biosynthesis od macromolecules from smaller molecular units into larger
complexes, most often associated with cellular growth and repair
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 ✔✔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 which form of phosphorylation? - ANSWER
✔✔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 ✔✔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 produces. Last, the electron transport
chain (ETC) produces 34 ATP via an oxidative phosphorylation event at
the plasma membrane.
What are the reactants of glycolysis? - ANSWER ✔✔Reactants are
defined as any molecules present and involved at the beginning of a
specific chemical reaction (ie) glycolysis. In terms of writing out a
chemical reaction, the reactants are everything located to the left of the
arrow. The reactants of glycolysis are glucose, the co-enzyme NAD+ and
ATP.
How are the TCA and ETC related? - ANSWER ✔✔The end products of
the Kreb's (TCA) cycle are used to fuel the electron transport chain. In
other words, as the Kreb's cycle (TCA) produces an abundance of
reduced electron carriers (NADH and FADH2), it fuels the ETC. As the
