Question
6. Reduction is when a molecule , while oxidation is when a molecule an electron or hydrogen atom. a. Loses, gains b. Transports, replaces c. Replaces, transports d. Gains, loses e. Fixes, catalyzes 7. What are redox reactions? Why are they important in transporting energy? What role do electron carrier molecules have in redox reactions and transporting energy? + 8. Which of the following equations represents aerobic respiration? a. 6CO, 6H,0 CGH1206 60, b. 6CO, 60, CH,O, + 6H,0 C. CH20, 60, + 6H,0 d. C,H,05 + 60, + 6CO, + 6H,O 6CO, 9. Which of the following is true regarding glycolysis? a. produces a glucose molecule! b. produces 4 Pytu vate molecules C-yields a net increase of 2 ATP D. yields one mo) cute OF NADH+HExplanation / Answer
6)d gains, loses
7)A redox reaction is a chemical reaction that involves a transfer of electrons between two species(atoms, ions or molecules). It can also be defined as any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron. The electron exchange leads to energy changes in important body reaction. The energy is tranferred from one chemcial species to another in this way.
Electrons carriers carry electrons from one part of an energy processing system to another(eg: electron transport chain), providing the necessary energy and reducing power to make chemical reactions occur. molecules such as NADH and FADH2 are important carrier molecules in aerobic respiration
8)d is the correct reaction. Glucose + oxygen from the environment is used up in photosynthesis and carbon dioxide and water is produced as products
9)yields a net increase of 2ATP
C6H12O6 + 2 NAD+ + 2 ADP + 2 P -----> 2 pyruvic acid + 2 ATP + 2 NADH + 2 H+.
