BIOD 101 MODULE 3 EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED)Which type of chemical reaction is used to join monomers in order to form polysaccharides and involves the loss of only water molecules? Answer Dehydration Describe the difference between anabolism and catabolism. Answer Anabolism refers to sum of all the synthetic energy-requiring biochemical reactions. Catabolism refers to the sum of all the energy-releasing degradation biochemical reactions Compare and contrast aerobic and anerobic respiration. Answer Aerobic respiration involves the consumption of oxygen, while anaerobic respiration can proceed in the absence of oxygen. Aerobic respiration yields the greatest amount of ATP and is the primary metabolic process used in the human body What are the three distinct processes of cellular respiration? Where do each occur in the cell? Answer Cellular respiration, in its entirety, can be thought of as three, distinct processes of (1) glycolysis, (2) the citric acid cycle, and the (3) electron transport chain. Glycolysis occurs in the cytoplasm, whereas the citric acid cycle and the electron transport chain take place in the mitochondria Describe the products of each of the two main phases of glycolysis Answer The first phase is known as the energy investment phase because two ATP molecules are used (recall the intent is to be making ATP, not using it) to split one glucose molecule into two intermediary molecules of glyceraldehyde 3-phosphate (G3P). The second phase is known as the energy payoff phase, which results in the production of 2 NADH, 2 ATP, and 2 pyruvate molecules What is the purpose of the Citric Acid Cycle? What are the main components of the CAC? Answer The Citric Acid Cycle (CAC), which can also be referred to as the Krebs Cycle, generates high energy molecules (NADH and FADH2) that will be later used to generate ATP in the Electron Transport Chain (ETC). The CAC involves a preparatory phase plus eight biochemical reactions Why is the CAC considered a cycle? Answer The CAC is referred to as a cycle because it begins and ends with a molecule of oxaloacetate True or False: Reaction 5 of the CAC results in the formation of citrate. Answer False; Reaction 1 of the CAC results in the formation of citrate. Reaction 5 results in formation of succinate What occurs in Reaction 8 of the CAC? Answer Malate is oxidized, and another NAD+ is reduced to NADH. The oxidation of malate results in the regeneration of oxaloacetate, thus bringing the cycle back to its beginning The first step of the CAC is a ____________ phase sometimes simply called ______ oxidation. Answer preparation; pyruvate True or False: The electron transport chain is an anabolic pathway. Answer False; the electron transport chain is catabolic pathway How does the electron transport chain generate ATP? Answer Notably, the ETC does not directly produce any ATP. However, establishing a proton gradient across the mitochondrial membrane will lead to the production of ATP via ATP synthase
