WGU Biochemistry C785 Exam Questions with Answers 2022 How many ATP are needed for gluconeogenesis to occur? -Correct Answer- 6 molecules of ATP are needed for gluconeogenesis. How many ATP are pr... oduced by glycolysis? -Correct Answer- 2 ATP are produced by glycolysis. What is the net loss/gain of ATP from the Cori cycle? -Correct Answer- The Cori cycle results in a net LOSS of 4 ATP per glucose molecule. Glucose is a monosaccharide. It can be used as the raw material to build which one of the following molecules? a. Nucleic acids b. none of these c. Proteins d. Glycogen -Correct Answer- d. Glycogen. Glycogen is a polysaccharide made up of glucose units. Glycolysis is the conversion of glucose to pyruvate. Is this a catabolic process of anabolic process? a. none of these b. both of these c. catabolic d. anabolic -Correct Answer- c. Catabolic. Catabolic pathways refer to the breakdown of larger molecules into smaller ones and often produce ATP as a result. Glycolysis is a catabolic process because a molecule of glucose is broken down into two molecules of pyruvate and two molecules of ATP. Which of the following is an accurate statement about glycolysis? a. glycolysis is the breakdown of a glucose molecule that requires the presence of oxygen b. glycolysis results in a net production of four ATP molecules c. all of these d. the final product of glycolysis are 2 molecules of pyruvate -Correct Answer- d. the final product of glycolysis are 2 molecules of pyruvate. True or False. Glucose is the only food source that can make acetyl Co-A. -Correct Answer- False In the presence of oxygen, the end products of glycolysis have the potential to enter which of the following pathways? a. glycolysis b. fermentation c. citric acid cycle d. none of these -Correct Answer- c. Citric acid cycle. In the presence of oxygen, pyruvate forms acetyl co-a and enters the citric acid cycle, while fermentation occurs in the absence of oxygen. In human cells, glycolysis takes place in the cytoplasm. The products of glycolysis will enter the __________ to continue with aerobic respiration. a. mitochondria b. cytoplasm c. nucleus d. ribosomes -Correct Answer- a. mitochondria. NADH and FADH2 are two cofactors made in the citric acid cycle. They then donate the _________ they gain in the citric acid cycle to the electron transport chain. a. ATP b. glucose c. Oxygen d. electrons -Correct Answer- d. electrons. Oxygen has a role as the terminal electron acceptor in the electron transport chain. [Show More]
