Hi. Unfortunately you didn't show what your textbook does about motivation. This prevents your question from being answered, as it directly asks for your textbook to be analyzed.
However, I will try to help you by showing you how you can find the answer to this question.
As you can see, all answer options refer to motivation. In this case, to answer this question, you should look in your textbook for all the topics where it addresses motivation, either explaining it or associating it with events and situations. You should read all these topics and understand how their author introduces the subject of "motivation" to you. After that, you should read all the answer options and identify the one that presents information similar to what you read in your textbook. That will be your answer.

In the presence of oxygen, one glucose molecule has the energy to make up to 38 ATP. The ATP production is determined by the following steps, (-2 ATP) glycolysis preparatory phase, (7-9 ATP) glycolysis pay-off phase, (5 ATP) oxidative decarboxylation of pyruvate and (20 ATP) Krebs cycle. One glucose which has 38 ATP hence was the summation of all the process mentioned that took place. All these process take place under the cellular function of cellular respiration.<span>
