Select all that apply. light CO2 O2 water sugar Question 2 Which of the following is not produced by the process of respiration? Sugar H2O ATP CO2 Question 3 Respiration is … anabolic because it breaks down sugar. catabolic because it breaks down sugar. catabolic because it builds CO2. anabolic because it builds CO2. Question 4 While Jill and Andre were studying for their Biology exam, Andre said, %u201CAnimals perform cellular respiration and plants perform photosynthesis.%u201D What about Andre%u2019s statement should Jill have told him was incomplete? Plants also perform cellular respiration. Animals also perform photosynthesis. Animals do not perform cellular respiration. There is nothing incomplete about Andre%u2019s statement. Plants do not perform photosynthesis. Question 5 Select the incorrect statement regarding respiration and fermentation from the list below. Respiration produces much more ATP than fermentation Both respiration and fermentation use organic molecules. Respiration produces acidic products, fermentation does not. Respiration uses oxygen, fermentation does not. Question 6 Which of the following processes requires oxygen? photosynthesis all of these processes fermentation cellular respiration Question 7 Which of the following organisms is capable of photosynthesis? Select all that spply. Plants Algae Fungi Mammals Question 8 Which of the following is an anabolic pathway? fermentation photosynthesis cellular respiration all of these processes Question 9 Which organelle captures energy, in the form of sunlight, in plant cells? chloroplast nucleolus mitochondrion plasma membrane cytoplasm Question 10 One way to explain how cellular respiration and photosynthesis relate to each other is to say that: Plant cells use the oxygen produced by respiration for photosynthesis. The two processes are not related. Cellular respiration is a series of reduction reactions while photosynthesis is a series of oxidation reactions. The use of oxygen by plants contributes to the greenhouse effect. The oxygen produced by photosynthesis, once released to the environment, is the oxygen able to be used as the electron acceptors for cellular respiration. Pathways and Regulations Quiz Question 1 How does the body react to rapid weight loss? Hunger increases and the metabolic rate goes down. Hunger decreases and the metabolic rate goes up. Hunger increases and the metabolic rate goes up. Question 2 What would be a typical regulatory system in a metabolic pathway? The pathway%u2019s product slows it down, so that the product is maintained at a constant level in the cell or organism. The pathway%u2019s product makes it go faster, so that more and more of the product builds up in the cell or body. Question 3 Which of the graphs in the figure best illustrates the activity of an enzyme as substrate concentration increases from 0 to the saturation point of the enzyme? Question 4 Which of the following are characteristics of metabolic pathways? Contain many intermediates. Are regulated. Each pathway has a key enzyme that catalyzes most of the reactions Are specific for each organism Are often reversible Question 5 The fundamental difference between competitive and non-competitive inhibition is: _________________________ the manner of binding of the substrate to the enzyme. the size of the active site of the enzyme. the manner of binding of the inhibitor to the enzyme. Question 6 Which best describes body weight regulation in a normal human who is living in a modern society? Our normal responses of appetite and metabolism tend to cause weight gain in modern societies, and they also tend to make weight loss difficult. Our normal responses of appetite and metabolism ensure that adults remain at a given normal body weight. Any change from this normal weight sets in motion responses that return the body to its normal weight. Question 7 Energy is stored in different forms in the body. ATP is very unstable and is put to use very quickly in cells. Other storage molecules last longer. Which gives the major energy stores of the body in the correct order? Short term: glycogen. Medium term: glucose. Long term: fat. Short term: glucose. Medium term: glycogen. Long term: fat. Short term: fat. Medium term: glycogen. Long term: glucose. Question 8 Which of the following regulatory mechanisms is described incorrectly? competitive inhibitor: binds to the active site of the enzyme enzyme modification: enzyme gains or loses a functional group feedback inhibition: product inhibits its own production substrate availability: more substrate increases enzyme activity (until it reaches saturation) All are correct Question 9 Cells or organisms tend to maintain steady internal conditions. What is the name for this property and ability of life? Reproduction Metabolism Adaptation Homeostasis Question 10 What is the connection between a person%u2019s genes and his or her metabolism? structural proteins encoded by genes regulate metabolic pathways DNA regulates metabolic pathways directly enzymes encoded by genes regulate metabolic pathways • Show less
