Study Notes
ATP-ADP Cycle
- Phosphorylation involves the addition of phosphate to an organic compound
- The main function of ATP in a cell is to provide energy
- ATP is regenerated in a cell through cellular respiration, where energy from the breakdown of glucose is used to phosphorylate ADP
Cellular Work
- Mechanical work in a cell involves the beating of cilia and contraction of muscles
Energy Source
- The source of free energy for phosphorylating ADP to form ATP is the energy from the breakdown of glucose
ATP Cycle
- The primary function of the ATP cycle is to provide energy for cellular processes
Photosynthesis
- Chlorophyll-containing membrane discs known as thylakoids are found in chloroplasts
- Carotenoids are plant pigments responsible for the yellow, bright red, and orange colors in vegetables and fruits
- Chlorophyll plays a crucial role in the chloroplast by absorbing light energy and transferring it to other molecules
- Plant pigments are important for absorbing specific wavelengths of visible light, which is necessary for photosynthesis
