Let f : R 2 â R 2 and g : R 2 â R be differentiable, and let ~a â R 2 be fixed. Suppose: f(~a) = [2, 3], g(~a) = , [D f(~a)] = [1 2, 3 4], [D g(~a)] = [3 â7] Here, expressions like  mean a 1 Ã 1 matrix (i.e., a scalar). The commas mean the start of another row in the matrix.
(a) Evaluate (fg)(~a). (b) Evaluate [D(fg)(~a)] h~ for h~ = [1, â1/2]
Acetyl CoA is the beginning of a metabolic pathway that produces most of the NADH and FADH for ATP production. When you starve, which of the following will produce the most Acetyl CoA?
Protein, carbohydrates, and lipid metabolism all produce the same amount
Free Oxygen radicals
Which of the following statements regarding the energy production roles in different environments is incorrect?
|All organisms must generate energy from the nutrients they obtain, typically through the oxidation of organic carbon to generate usable energy in the form of ATP.|
|In glycolysis, glucose is oxidized to pyruvate, which generates two ATP and 2 NADH molecules.|
|In the presence of oxygen the pyruvate can be further oxidized to generate even more ATP via respiration.|
|In the absence of oxygen, further oxidation of pyruvate cannot occur and instead the pyruvate is converted to a waste product like creatinine at the expense of the NADH produced during glycolysis.|
|All of these statements are correct.|
