The Pentose Phosphate Shunt (AKA: Pentose Phosphate Pathway, PPP)

The Pentose Phosphate Shunt (AKA: Pentose Phosphate Pathway, PPP) Uses Glucose 6P to produce 3, 4, 5, 6 and 7 carbon sugars. In the process of doing this it reduces NAD+ to NADPH which is needed for reductive biosynthesis. . NADPH is needed for synthesis of fatty acids.

An Overview of Photosynthesis

An Overview of Photosynthesis. Most of the energy used by almost all living cells ultimately comes from the sun plants, algae, and some bacteria capture the sunlight energy by a process called photosynthesis only about 1% of the available energy in sunlight is captured.

Uracil is the precursor of all pyrimidine nucleotides.

Pyrimidine biosynthesis. Uracil is the precursor of all pyrimidine nucleotides. N1 and carbons 4, 5 and 6 are derived from ASP. C2 and N3 are derived from carbamoyl phosphate. The carbamate group of carbamoyl phosphate is activated for group transfer (cf. ARG biosynthesis) . .

What happens during photosynthesis?

What happens during photosynthesis?. Energy from the sun is absorbed by the chlorophyll molecules in the thylakoid membranes of the chloroplast. Water is also absorbed by the roots and enters the thylakoid membranes.
