Electron Transport Chain

The electron transport chain, also known as the electron transport system, is a group of proteins that transfer electrons through a membrane within mitochondria to create a gradient of protons that drives adenosine triphosphate (ATP)synthesis. The cell u…

Metabolism

Picture a campfire. It keeps the body warm on a cold night and provides light. To ensure that the fire keeps burning, fuel needs to be added(pieces of wood in this case). When a small piece is added, the fire burns bright for a bit and then dies down unl…

Cellular Respiration

Cellular respiration is the cellular process involved in the generation of adenosine triphosphate (ATP) molecules from the organic nutritional source obtained from the diet. It is a universal process observed in all types of life forms. The glucose (chem…

2. Glycolysis yields: a. more ATP than a cell needs to survive b. 36 ATP only when O2 is used during this process c. 2 ATP in both aerobic and anaerobic organisms d. less ATP than it uses up during the process 3. Photosynthesis provides the following to living systems: a. lipids and oxygen. b. atmospheric oxygen and chemical energy c. organic "fixed" carbon. d. hydrophyllic compounds. e. b and c 4. Gamma rays: a. are necessary for plants to photosynthesize b. cause cells to begin to divide c. are high energy short wavelength rays from the sun d. are low energy long wavelengths rays from the sun

Why must nitrogen fixation occur in an anoxic (i.e., oxygen-free) environment? a)Because H2 is an additional product of nitrogen fixation, and the combination of H2 and O2 would cause the cell to combust. b)Oxygen poisons the dinitrogenase enzyme by entering the FeMo cluster c)Oxygen competes as an electron acceptor in the ETC, so electrons cannot be passed to N2. d)Oxygen "steals" electrons from the dinitrogenase reductase, producing free radicals.

6. The CO2 released when we exhale is produced by:a) Glycolysis (glucose to pyruvate)b) The respiratory chain (electron transport chain)c) By pyruvate decarboxylation and by the TCA cycle.d) Fermentatione) All of the above
