1. acquired through foods
II. Adenosine Triphosphate
A. Energy storing compounds in living things(plants and animals)
B. Obtain it from glucose
C. Structure of ATP
i. Adenine (nitrogen base)
ii. Ribose (5- carbon sugar)
iii. 3 phosphate groups
D. Energy is in the bonds between the phosphates.
E. Break the bonds to release energy. (Done by enzymes)
III. Photosynthesis (general information)
A. Process of converting sunlight energy into chemical energy. Sugar/glucose
B. Chemical equation:
Carbon dioxide + water + light -------glucose + oxygen
Know this 6CO2 + 6H2O + Light -------C6H12O6 + 6O2
C. Process is started by sunlight hitting pigments in plant cells.
D. Main pigment in plants is Chlorophyll.
i. Green chlorophyll absorbs mostly red and blue light (reflects green light)
ii. This is why we see plants as green!White light contains all the wavelengths (all the colors)
