Interpretation Introduction

Interpretation:

The fraction of energy trapped as high-energy electrons for 700-nm light absorbed by photosystem I should be determined.

Concept introduction:

The energy possessed by releasing electrons can be calculated as Gibbs free energy, by the following reaction.

ΔG=nFE

A photon can be introduced as a piece of energy which has no mass. The relationship between the energy of a photon and its wavelength can be expressed with the following Planck-Einstein equation.

Biochemistry What is the process of "transamination" in either the muscles or the liver, that involves keto acid or glutamic acid? Please explain how the steps work. Thank you!
Biochemistry Please help. Thank you What is the importance of glutamic acid in the metabolism of nitrogen from amino acids? (we know therole; it’s used to remove the nitrogen from amino acids so that the remaining carbon skeleton can bebroken down by the “usual” pathways, but what is the important, unique role that only glutamicacid/glutamate can do?)
