Question:

What is the de Broglie's wavelength of an electron that has 1203 m/s velocity?

William B.
Answer:

wavelength = h/p according to de Broglie. The p = mv, which is the definition of momentum. wavelength = 6.626e-34/(9.109e-31 * 1203) = 6.04e-7 m.

Question:

What is the function of Rubisco in the Calvin Cycle?

William B.
Answer:

The enzyme helps join the carbon dioxide and 5 carbon molecule that gets recycled in the Calvin cycle. After the molecules are joined, they form a 6-carbon molecule intermediate, which becomes unstable and breaks down into 2 3-carbon molecules.
