Carbon dioxide

Water

Heat

Lactic acid

Answer 1

Lactic acid

Question 2

Answer 2

Glucose; oxygen and pyruvate

Question 3

1. ATP is the energy stored in our cells. The ultimate source of this energy comes fromPhosphateGlucoseSunlightADP

Answer 3

Sunlight

Question 4

1. Of the following processes, which produces the largest amount of ATP?GlycolysisLight reaction in photosynthesisElectron transport chain and oxidative phosphorylationAnaerobic respiration

Answer 4

Electron transport chain and oxidative phosphorylation

Question 5

1. The metabolic pathway that involves the oxidation of glucose to pyruvate is calledglycolysis.oxidative phosphorylation.the citric acid cycle.fermentation (anaerobic respiration).

Answer 5

glycolysis.

Question 6

1. The enzymes of the Krebs cycle are located in thecytoplasm.inter-membrane space of mitochondria.vesicles of the ER.outer membrane of the mitochondria.matrix of the mitochondria.

Answer 6

matrix of the mitochondria.

Question 7

1. NAD and FAD areoxidised to NADH and FADH during glycolysis and the citric acid cycle.reduced to NADH and FADH by the electron transport system.recycled from NADH and FADH by the electron transport system.converted to NADH and FADH in reactions coupled to the synthesis of ATP.

Answer 7

recycled from NADH and FADH by the electron transport system.

Question 8

1. A process common to all living organisms, aerobic and anaerobic, isglycolysis.fermentation forming lactic acid and ethanol.the Krebs cycle.electron transport chain reactions.

Answer 8

glycolysis.

Question 9

1. The chief energy currency of all cells is a molecule calledNADH.FADH.ATP.ADP.

Answer 9

ATP.

Question 10

1. Instruction: Answer to this question requires you to google outside the lecture notes. The electron carriers of the respiratory electron transport chain areembedded in the plasma membrane of aerobically respiring prokaryotic cells.embedded in the plasma membrane in all prokaryotic cells.absent in all prokaryotic cells.embedded in the inner mitochondrial membrane of aerobically respiring prokaryotic cells

Answer 10

embedded in the plasma membrane in all prokaryotic cells.

Question 18

Chem equation for skeletal

Answer 18

Glucose–> lactic acid

Question 19

difference between ANA AND AEROBIC!!!

Answer 19

Aerobic: has Co2 and more ATP

takes place cytoplasm, occurrence in skeletal and yeast cells.
