An athlete uses ATP (another chemical) as fuel for a sprint when a glucose molecule is broken down. The procedure generates heat as a byproduct. In what ways do you think the sprint's initial and ending energy kinds differ? Do you think this is an endothermic reaction?

Suppose that a cow is launched into space, far from the Sun, wearing a suit that provides it with oxygen but very little insulation. Estimate how long it will take the cow to radiate enough heat to lower its body temperature by 2C , wherein hypothermia will begin to set in. (Note: You will have to estimate whatever numerical parameters that you think are relevant to this problem; there is a wide range of “correct answers”.)

Which of the following statements is NOT true?   None of the other four answers (all are true) The energy required to cause a chemical reaction to occur is called the activation energy Decomposition (degradation, catabolic) reactions are usually endergonic Chemical reactions in living cells are catalyzed by enzymes Enzymes increase the probability that a chemical reaction will take place by lowering the activation energy

If there is a shortage of glucose in the body, the body then utilizes fats as a source of ATP. Though ATP production from the metabolism of fats is significantly higher than carbohydrates, lipid metabolism is harmful for the long run. What is the eventual number of ATP molecules produced during the metabolism of lipids and why is using lipids as the primary energy source harmful? Write brief sentences.

The Na+/K+/ATPase is the protein that creates an electrochemical gradient in your cells. It accomplishes this by: (select all that apply)   A. Pumping Na+ from inside to outside the cell   B. Pumping Na+ from outside to inside the cell   C. Pumping K+ from inside to outside the cell   D. Pumping K+ from outside to inside the cell

______________ is a molecule that forms when a phosphate compound splits off from a molecule of _______________, releasing energy that can now do work for the cell. This molecule, when formed due to this removal of a phosphate compound, can be thought of as a "dead battery". It can become "recharged" when the phosphate compound is added back onto this molecule.   Question 1 options:   Reduced nicotinamide adenine dinucleotide (NADH), adenosine triphosphate (ATP)   None of the other answers are correct.   Sucrose, glucose   Zymase, pyruvate   Adenosine diphosphate (ADP), adenosine triphosphate (ATP)   Adenosine triphosphate (ATP), acetaldehyde   Adenosine triphosphate (ATP), adenosine diphosphate (ADP)   Lactate, ethanol

What is the net yield of ATP from glycolysis?   Four ATP   Thirty-eight ATP   Two ATP   Thirty-four ATP
