Textbook Question
Chapter 5, Problem 13IMT
For each statement, identify which major theme is evident (the relationship of structure to function, information flow, pathways that transform energy and matter, interactions within biological systems, or evolution) and explain how the statement relates to the theme. If necessary, review the themes (see Chapter 1) and review the examples highlighted in blue in this chapter.
13. Enzymes unravel and stop functioning if the environment gets too hot.

write a 5 sentence min. paragraph on enzymes. Explain what type of molecule they are, what their role is, a real life example, and what causes them to fail in the human body.
Statement A: The flow of matter across the earth’s subsystems involves the transformation of matter into energy.
Statement B: The breakdown of glucose molecule into H2O and H2O in the process of cellular respiration corresponds to the formation of a chemical form of energy adenosine triphosphate
Both statements A and B are correct
Statement A is correct, statement B is incorrect.

Neither statement A nor statement B is correct.
Which statement about enzymes is true?
An enzyme functions to decrease the rate of a chemical reaction.
Enzymes are proteins that function as catalysts in nonliving things.
Each enzyme can catalyze many different biochemical reactions.
Enzymes and substrates fit together like a lock and key.
