Citric acid cycle Main article: Citric acid cycle This is also called the Krebs cycle or the tricarboxylic acid cycle. The antenna system is at the core of the chlorophyll molecule of the photosystem II reaction center.
The hydrogen ions are released in the thylakoid lumen and therefore contribute to the transmembrane chemiosmotic potential that leads to ATP synthesis.
In aerobic conditions, the process converts one molecule of glucose into two molecules of pyruvate pyruvic acidgenerating energy in the form of two net molecules of ATP. An electron transfer system a series of chemical reactions carries the two electrons to and fro across the thylakoid membrane.
A leaf may be viewed as a solar collector crammed full of photosynthetic cells. There is a lot of water on the earth, and every water molecule is composed of two hydrogen atoms and one oxygen atom.
During the pay-off phase of glycolysis, four phosphate groups are transferred to ADP by substrate-level phosphorylation to make four ATP, and two NADH are produced when the pyruvate are oxidized.
This means that animals have to survive solely through respiration. The energy stored in the phosphate bond is used in other cellular reactions and is often regarded as the energy "currency" of the cell.
Glycolysis Out of the cytoplasm it goes into the Krebs cycle with the acetyl CoA. Let me briefly summarize what both processes do: Photosynthesis Is the chemical process where plants can capture and organically fix the energy of the sun.
Sufficient energy ionises the molecule, with the electron being 'freed' leaving a positively charged chlorophyll ion.
