Cellular respiration canbe broken down into

Thus, so far, the following ATP have been made: 2 ATP ---- Glycolysis
2 ATP ---- Krebs Cycle
4 ATP ---- TOTAL
Also, so far, the following H-atoms have been made:
2 NAD-H-H ---- Glycolysis
2 NAD-H-H pyruvic acid -> acetic acid
6 NAD-H-H ---- Krebs Cycle
2 FAD-H-H ---- Krebs Cycle
24 H-atoms -- TOTAL



The H-atoms are used in the final phase of aerobic respiration - the electron transport system.

A comparisonbetween Photosynthesis and Respiration:

Photosynthesis and cellular respiration are similar in that they both undergo chemiosmosis.

Cellular respiration supplies energy in the form of ATP.

Organisms that use cellular respiration, such as humans, use that oxygen to kick-start and propel the reactions of cellular respiration, especially those occurring during the Electron Transport Chain.

during cellular respiration, ..

Oxidative phosphorylation synthesizes the bulk of a cell’s ATP during cellular respiration. A , in the form of a large proton concentration difference across the membrane, provides the energy for the membrane-localized (a molecular machine) to make ATP from ADP and inorganic phosphate (Pi). The proton gradient is generated by a series of oxidation-reduction reactions carried out by protein complexes that make up an electron transport chain in the membrane. The term oxidative phosphoryation, then, refers to phosphorylation of ADP to ATP coupled to oxidation-reduction reactions.

This marks the END of glycolysis, but not the end of respiration.





To summarize, glycolysis split a glucose into 2 pyruvic acid molecules using 2 ATP's , while making 4 ATP's, in the process.

Respiration and photosynthesis use ..

The NAD and FAD are then reduced in the following few steps so that their reduced forms NADH and FADH2 may carry the electrons onto the next part of cellular respiration.

Cellular Respiration and photosynthesis are two very complex ..

The electron transport chain pumps the H-atoms into the intermembrane space of the mitochondria (as H-ions) and chemiosmosis makes ATP from the hydrogen ions.




Now we will cover aerobic respiration in detail, starting with the pyruvic acid that was produced by glycolysis.

Though, they both are metabolic pathways with their own type of function and cycle.

Obviously aerobic is more efficient than anaerobic respiration because aerobic respiration does produce ATP while anaerobic makes no ATP, it only keeps inefficient glycolysis working.





While glycolysis and anaerobic respiration occur in the cytoplasm of a cell, aerobic respiration occurs in the mitochondria of a cell.

in photosynthesis and cellular respiration?

Photosynthesis uses those products from cellular respiration as its reactants and in turn produces glucose and oxygen- the reactants needed for cellular respiration.

The
2 NAD-H-H will be used later in aerobic respiration.




The pyruvic acid produced by glycolysis will then be further broken down by aerobic or anaerobic respiration.
