Pick something you are interested in, something you'd like to think about and know more about

Then do some background research on the topic.

Decide whether you can state a hypothesis related to the topic (that is, a cause and effect statement that you can test), and follow the strict method listed above, or whether you will just observe something.

Design and carry out your research, keeping careful records of everything you do or see and your results or observations.

Construct an exhibit or display to show and explain to others what you hoped to test.

Write a short report that also states the same things as the exhibit or display, and also gives the sources of your background research.

Practice describing your project and results, so you will be ready for visitors to your exhibit at the science fair.

Which of the following accurately describes the role of energy in cellular respiration?
zmey [24]

Answer:

The correct answer is option energy is a product.

Explanation:

Cellular respiration is a process in which oxidation of food or glucose takes place to produce energy. This process proceeds in four processes: glycolysis, oxidative carboxylation, Krebs cycle and electron transport chain.

All of this process produces energy in the form of ATP or energy equivalents like NADH and FADH₂.  

1. Glycolysis produces- 2 ATP, 2 NADH,  

2. Oxidative carboxylation produces- 2 NADH,  

3. Krebs cycle produces- 2 ATP, 6 NADH AND 2 FADH₂ and  

4. Electron transport chain produces at last- 24 ATP from these reducing equivalents.

Thus, option energy is a product is a correct option.
