1-Dont try to cram or spend more time here just read it fast and cover syllabus then practice MCQ's cheptor of same topic to check your progress. . |
2-Wrong options are also given but dont concentrate there, Right answer is in bold format. |
Q1 ⇒ Which of the following best explains about the usefulness of the production of ethanol in yeast cells under anaerobic conditions? The process regenerates NAD+, which is required for glycolysis [other wrong options] [Discuss in forum] Ethanol keeps the electron transport system functioning Yeast would be unable to activate the enzymes of the Krebs cycle without ethanol The process generates oxygen, which is required for glycolysis |
Q2 ⇒ The amount of energy (cal/mole) in an ATP molecule produced by a cell from glucose by fermentation is exactly or approximately equal to aerobic metabolism [other wrong options] [Discuss in forum] greater than aerobic metabolism less than aerobic metabolism none of the above |
Q3 ⇒ Before most molecules can enter the Krebs citric acid cycle, they must be converted to acetyl-CoA [other wrong options] [Discuss in forum] citric acid oxaloacetic acid NADH or FADH |
Q4 ⇒ The number of ATP molecules produced from one glucose molecule by a bacterium producing lactic acid is approximately equal to producing ethanol [other wrong options] [Discuss in forum] greater than producing ethanol lesser than producing ethanol none of these |
Q5 ⇒ Organisms can synthesize ATP by oxidative phosphorylation when they pass electrons to oxygen through an electron transport system containing cytochromes [other wrong options] [Discuss in forum] ferment oxidize glucose to pyruvate pass electrons from the oxidation of chlorophyll through an electron transport system |
Q6 ⇒ Glucose can be broken down to pyruvate by Entner-Doudoroff pathway [other wrong options] [Discuss in forum] tricarboxylic acid cycle both (a) and (b) none of these |
Q7 ⇒ Which one of the following is produced in the greatest numbers during one turn of the Krebs cycle? NADH [other wrong options] [Discuss in forum] Acetyl-CoA FADH2 ATP |
Q8 ⇒ Most bacterial fermentations yield how many net ATP molecules per molecule of glucose? 2 [other wrong options] [Discuss in forum] 1 4 6 |
Q9 ⇒ The enzymes that catalyze the reactions of the Krebs cycle are found in which subcellular organelle of eukaryotes? Mitochondrion [other wrong options] [Discuss in forum] Chloroplast Ribosome Endoplasmic reticulum |
Q10 ⇒ Suppose a eukaryotic cell had a mutation that prevented the production of cytochrome c. As a result of this mutation, which of the following processes would not occur? Cellular respiration [other wrong options] [Discuss in forum] Photosynthesis Mitosis Cell wall synthesis |
