Question

Starting with a GLUCOSE molecule and ending with ATP, indicate the correct chronological sequence that each of the following chemical reactions would occur in a cells normal metabolic processes. Glucose phosphorylation by Hexokinase into Glucose-6-Phosphate Pyruvate transformation into Acetyl-CoA by dehydrogenation & expulsion of CoA Isomerization of G-6-P into Fructose-6-Phosphate Isocitrate changed into a-ketoglutarate followed then by transformation into Succinyl-CoA Dihydroxyacetone phosphate GIjccraJdehyde-3-phosphate Nicatinamide adenine dinucleotide "passing" electrons to Complex I of the ETS G-3-P + Pi rightarrow 1, 3 Bisphosphoglycerate (catalyzed by Triose Phosphate Dehydrogenase) Cytochrome-c "passing electons to Complex IV: Complex IV then "passing" electrons to O_2 to make water Phosphoenolpyruvate conversion to Pyruvate by Pyruvate Kinase ADP + P_ i rightarrow Adenosine triphosphate via ATP Synthase action (oxidative phosphorylation) a. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 b. 2, 4, 6, 8, 10, 1, 3, 5, 7, 9 c. 1, 2, 8.7, 4, 5, 3, 9, 10, 6 d. 1, 3, 5, 7, 9, 2, 4, 6, 8, 10 e. 2, 3, 4, 5, 6, 10, 9, 8, 7, 1 Which substances below could be observed either entering or leaving a mitochondrion? Oxygen Pyruvate Glucose Adenosine Triphosphate CO_2 Carbon monoxide gas a. 1, 2, 3 b. 2, 4, 6 c. 1, 2, 4, 5 d. 1, 3, 5, 6 e. 1, 2, 3, 4, 5, 6 Which of the following statements is NOT true of saliva? a. It moistens food and aids in compacting of the bolus b. It contains enzymes that begin the breakdown (digestion) of proteins. c. It cleanses the mouth. d. It dissolves food chemicals (tastants) so that they can be "tasted." e. All of the statements above are true The major source of the bicarbonate-rich buffer solution is secreted by which digestive organ? a. pancreas b. salivary glands c. liver d. stomach e. gallbladder

Explanation / Answer

94. d.In this process the sugar molecules splits and resulting in energy.

95.c. Oxygen is requir for oxidation process and the end product of glycolysis pyruvate enters into mitochondria and through the preocess of electron transport chain it releases energy in the form of ATPand also it releases carbon di oxide.

96.b. saliva which is present in the buccal cavity does not breakdown the proteins. protein digestion takes place in the stomac.and it can be doen by the gastric juice wich is present in stomac.

97. a. pancrease secrets buffers solution and water.
