Question
Which of the following is not true of glycolysis? A) it splits glucose to form two molecules of pyruvate B) it begins the oxidation of glucose C) it produces a small amount of ATP D) it generates NADH+H E) it oxidizes glucose to carbon dioxide 1. 2. A biochemist has synthesized a drug that blocks phosphofructokinase. This drug would not be a good antibacterial treatment for human use because A) bacteria do not perform glycolysis. B) glycolysis can occur without the action of enzymes 0 C) glycolysis produces so little ATP that the drug will have little effect D) human cells also perform glycolysis so the drug might also poison them E) many pathogenic bacteria are facultative anaerobes so they don't need to perform glycolysis 3. The following is incorrect regarding the statement "A small amount of ATP is made in glycolysis: A) The process takes place through substrate-level phosphorylation. B) Enzymes producing ATP from ADP Pi, coupled with AGExplanation / Answer
1.Glycolysis starts the oxidation of glucose. It produces small amount of ATP and generates NADH + H+. Glycolysis finally splits glucose into two molecules of pyruvate.
But Glycolysis cannot oxidize glucose to carbon dioxide. Hence option "E" is the correct answer.
2. Glycolysis occurs in all most all cells or all living organisms starting from prokaryotes to developed multicellular eukaryotes. Phosphofructokinase is the enzyme that catalyzes the conversion of fructose-6-phosphate to fructose1,6-bisphosphate, which is the 3rd step in the glycolysis.
if the drug can block phospho fructokinase, then it can block the glycolysis of both the bacteria and human cells also. hence this drug can become poison for human. So the correct answer is option "D".
3. Substrate level phosphorylation in the glycolysis causes the small amount of ATP to be made. The enzymes that are involved in making ATP from ADP and Pi are called Kinases. In glycolysis total 4 ATP molecules are made with the net investment of 2 ATP molecules. in the second half of the reactions of glycolysis, the enzymes phospho glycerate kinase and pyruvate kinase are responsible for the synthesis of ATPs.
The substrate level phosphorylation does not depend on delta pH and voltage gradiets. Hence the correct answer is option " D ".
4. NADPH + H+ is the reductant that is used in the anabolic pathway. In mammalian muscle cells under anaerobic conditions by anaerobic respiration of the muscle cells "lactate" is produced. The product of the reduction of the pyruvate and the entry substance of the krebs cycle is "Acetyl Co-A". In catabolic reactions from the reductant that is produced is NADH + H+.
Cholesterol does not get produced by the bacterial cells in their anaerobic conditions. So the option "C" is the correct answer.
