Biology 1111 Chapter 6 Questions And Correct Answers.

Cellular respiration - Answer the process of making ATP through the breakdown of glucose, which takes place in the Mitochondria C6H12O6 + 6O2 ---> 6CO2 + 6H2O + ATP Autotrophs - Answer An organism that makes its own food, thereby sustaining itself without eating other organism or their molecules Heterotrophs - Answer An organisms that obtains organic food molecules by eating other organisms or substances derived from them Anaerobic - Answer No oxygen (outside of cell) Aerobic - Answer Needs oxygen (inside of cell) Glycolysis - Answer the "splitting of the cell," Anaerobic, cytoplasm, Reactants: Glucose Products: 2 Pyruvates + 2 NADH+ 2 ATP Formation of Acetyl CoA - Answer Carboxyl group is leaved off of a pyruvates (3 Carbons) and released as O2; its aerobic, Mitochondrial Matrix, Reactants: 2CoA Products: 2 acectyl CoA + 2NADH + 2CO2 Citric Acid Cycle ( kreb's cycle) - Answer Uses 1 ATP per cycle, Aerobic, Mitochondrial Matrix Reactants: 2CoA Products: 3 NADH + 1 FADH + 2CO2 Electron Transport Chain - Answer Oxidative phosphorylation= the production of ATP using energy from the breakdown of organic molecules; Aerobic, inner mitochondrial matrix Regulation of cellular respiration - Answer The cell regulates the concentration of ATP very tightly, If excess ATP are formed (more than the cell is using) cellular respiration will be Inhibited Chemiosmosis - Answer the potential energy of this concentration gradient is used to make ATP
