ATP Production. In photosynthesis, light provides the energy required to build organic molecules like glucose. In respiration, organic molecules such as glucose are broken down to release energy for the synthesis of ATP. Chemiosmosis. The diffusion of protons from a region of high concenration to low concentration through a partially permeable

Our broad knowledge in cell and molecular biology qualify us to participate in the via protease activity, LDH and cell free DNA, metabolic activity, ATP amount etc. We offer molecular biological analysis on both gene and protein level.

Learn the structure of ATP (adenosine triphosphate) and how this structure links to the function of it being an immediate source of energy.

This forms a molecule which is unstable and immediately breaks down into two three-carbon molecules called triose phosphate (TP). Hydrogen is removed from TP to convert it into pyruvate. The hydrogen is transferred to a coenzyme called NAD to form reduced NAD (NADH).
