Order the following sources of energy (from first used to last used) when muscles are called upon to do extensive work:(a) Fatty acids from triacylglycerols(b) ATP(c) Glycogen(d) Creatine phosphate(e) Glucose
Give two SPECIFIC examples of when, where, and why temperature and pH are important to the activity of enzymes in your body.
For each of the four possibilities listed below (a through d), only one answer is correct and the others are false. Identify the correct statement and explain why the others are false. In your answer, write CORRECT next to the statement that you think is true, and ONLY for the ones that you think are false, explain what is wrong with the statement .
When glucose reacts with ATP to form glucose-6-phosphate (as shown on the figure below):
1. The synthesis of glucose-6-phosphate is exergonic
2. ADP is at a higher energy level than ATP
3. Glucose-6-phosphate is at a higher energy level than glucose
4. Because ATP donates a phosphate to glucose, this is not a coupled reaction
