Sciences > Cellular Biology How photosynthesis works

16 of 29

Photosynthesis is the process by which food is made by plants. The whole process is split into two stages; the light dependent stage and the temperature dependent stage (Calvin cycle). The light dependent stage occurs in grana of each chloroplast and involves light being absorbed by chlorophyll or other associated pigments. ... More..

Sciences > Cellular Biology Structure and function of the cell membrane

5 of 8

The cell membrane is known to consist of protein and phospholipid molecules. The arrangement of these is still unknown but most evidence supports the fluid mosaic model of cell membrane structure. This means the membrane consists of a fluid bilayer of constantly moving phospholipid molecules containing a patch mosaic of prot... More..

Sciences > Anatomy The body's regulation of blood sugar and glucose

4 of 6

Glucose can be rapidly converted into glycogen for storage then back to glucose when required. This glycogen can be stored in the liver. When the blood glucose level falls the decrease is detected by receptors in the pancreas. The pancreas then releases more glucagon and less insulin. This stimulates the liver enzymes to con...
