of energy)
2) What are the two metabolic pathways of photosynthesis? -- Answer ✔✔ Light
reactions and Calvin Cycle
3) Where is chlorophyll located? -- Answer ✔✔ Thylakoid
4) What are some examples of electron carriers in cellular respiration? -- Answer
✔✔ FAD+, FADH2, NADP+, NADPH, NAD+, NADH
5) Dephosphorylation -- Answer ✔✔ loss of a phosphate group
6) Phosphorylation -- Answer ✔✔ adding a phosphate group
, 7) What are the metabolic pathways of cellular respiration? -- Answer ✔✔
Glycolysis, Oxidation of Pyruvate, Citric Acid Cycle (Krebs Cycle), Oxidative
Phosphorylation
8) Is oxygen needed for glycolysis? -- Answer ✔✔ No
9) What are the inputs of glycolysis? -- Answer ✔✔ glucose, 2 ATP, 2 NAD+
10) What are the outputs of glycolysis? -- Answer ✔✔ 2 pyruvate, 2 NADH, 4 ATP,
2 ADP
11) How would the activation energy of a catalyzed reaction compare to a
noncatalyzed reaction? -- Answer ✔✔ The activation energy of the catalyzed
reaction would be less than the the activation energy of a noncatalyzed reaction
(REMEMBER: Delta (Triangle Thing) G does not change if the reaction is catalyzed
or not)
12) In the cellular respiration formula, C6H12O6 + 6 O2 → 6 CO2 + 6 H2O +
Energy, which one is being reduced and which one is being oxidized? -- Answer
✔✔ Glucose is oxidized, O2 is reduced

phosphorylation occur in eukaryotes? -- Answer ✔✔ Mitochondrial matrix
(mitochondria)
14) If a molecule loses an electron in a redox reaction, is the molecule oxidized or
reduced? -- Answer ✔✔ the molecule is oxidized
15) If you are working out, what type of process will your muscles use when they are
lacking oxygen? -- Answer ✔✔ Lactic Acid Fermentation
