advantage over other early life forms was their ability to perform photosynthesis. They contain a blue photo reactive pigment that can absorb the energy from the sunlight and use it to produce nutrients for the cell. During this process‚ water molecules are broken down into oxygen and hydrogen atoms which are then released in the air. In the very early days of life‚ Earth was populated only by anaerobic bacteria that didn’t need oxygen to survive. When cyanobacteria first made their appearance and started

(limited). What happens to cellular respiration when all of the cell’s NAD+ has been converted to NADH? If NAD is unavailable‚ the cell is unable to conduct any processes that involve the conversion of NAD+ to NADH. Because both glycolysis and the Krebs cycle produce NADH‚ both of these processes shut down when there is no available NAD+. 5. If the Krebs cycle does not require oxygen‚ why does cellular respiration stop after glycolysis when no oxygen is present? When no oxygen is present‚ oxidative

This report will overview the redox reaction - cellular respiration: C5H12O6 + 02 → 6CO2 + 6H2O + Energy and it’s use with the human body. Cellular respiration is a chemical process providing the body with usable and fast source of energy in the form of ATP. Along with ATP cellular respiration also produces CO2‚ H2O and Heat. This is an organic redox reaction. Redox reactions Redox reaction occur when there is a movement of electrons between atoms. Part of a redox reaction include: Oxidising Agent:

CELLULAR RESPIRATION -is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP)‚ and then release waste products. The reactions involved in respiration are catabolic reactions‚ which break large molecules into smaller ones‚ releasing energy in the process as weak so-called "high-energy" bonds are replaced by stronger bonds in the products. Respiration is one of the key

questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP)‚ and then release waste products. The reactions involved in respiration are catabolic reactions that involve the redox reaction (oxidation of one molecule and the reduction of another. Respiration is one of
