BIOCHEMICAL PATHWAY – A series of reactions linked
CELLULAR RESPIRATION- Some energy that is released from organic compounds is released by cells in another set of biochemical pathways.
chemical energy which they primarily store in carbohydrates.Heterotrophs obtain food by eating Autotrophs or other heterotrophs that feed on autotrophs.Autotrophs use the biochemical pathways to manufacture organic compounds from Carbon dioxide and water to create a carbohydrate and molecular oxygen is released Cellular respiration is a metabolic process by which cells generate energy in the form of ATP from the food molecules and release waste products carbon dioxide and water. Both Heterotrophs and Autotrophs use Cellular Respiration
- When a white lights reflects off an object different colours will be bounced off, However the various colours will react differently if the object contains a pigment
- Pigments absorb certain colours more strongly than others
- By absorbing certain colours, a pigment subtracts those colours from the Visible spectrum
- Colour transmitted by the pigment no longer appears white but rather the light wave that is being reflected
- Chlorophyll a - specific form of chlorophyll used in oxygenic photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light- Chlorophyll b - Chlorophyll b helps in photosynthesis by absorbing light energy. It is more soluble than chlorophyll a in polar solvents because of its carbonyl group.
- Its color is yellow, and it primarily absorbs blue light.- Called an accessory pigment because it assists
Chlorophyll a in capturing light energy
- By absorbing the accessory pigments enable plants to capture more of the energy in light
- During the fall many plants lose their chloroplasts and their leaves take on the rich hues of the carotenoids
