BIO 101 METABOLISM UNIT ASSESSMENT Metabolism Unit Assessment Attempt 1 of 2 Started: 04/06/2016 10:32 PM BST Submitted: 04/07/2016 1:45 AM BST Score: 73% Points: 110 out of 150 Question 1 Points: 0 out of 10 Which of these is true for photosynthesis, respiration and fermentation? • All of these convert light energy into chemical energy. • All of these use glucose as a starting material. • All of these occur in the mitochondria. • All of these produce heat as a result of energy conversions. Feedback Incorrect. Photosynthesis produces (rather than uses) glucose. Question 2 Points: 10 out of 10 Glucose molecules provide energy to power the swimming motion of sperm. In this example, the sperm are changing • chemical energy into potential energy. • chemical energy into kinetic energy. • kinetic energy into potential energy. • kinetic energy into chemical energy Feedback Correct! Potential chemical energy is converted to the energy of motion. Question 3 Points: 10 out of 10 Which of these is inhibited by excess glucose concentrations? • None of these • Photosynthesis • Fermentation
