## Questions

### Subject: Biochemistry

With respect to proteins, what does the primary structure refers to?

It only refers to the ordered sequence of amino acids in a polypeptide.

### Subject: Biology

How does Adenosine Tri-phosphate (ATP) gets produced in eukaryotic cells?

In eukaryotic cells the ATP generation processes occur within mitochondria. Electrons that are passed through the electron transport chain ultimately generate free energy capable of driving the phosphorylation of ADP through an enzyme called ATP synthase.

### Subject: Calculus

A rectangle with sides parallel to the coordinate axes is to be inscribed in the region enclosed by the graphs of y = x^2 and y = 4 so that its perimeter has maximum length. Find the dimensions of the rectangle of largest area that has its base on the x-axis and its other two vertices above the x-axis and lying on the parabola y = 12 − x^2

Let (x, 0) be the bottom right vertex of the rectangle. The question is to maximize f(x) = 2x(12 − x^2), x ∈ (0, 2√3). The only critical number is x = 2. The length of the rectangle with the largest area is 4 and its height is 8
