Document Summary
After 3 turns of calvin cycle, g3p molecules formed; basic building blocks for carbohydrate molecules. 5 or more carbons fold into ring form, not linear. Glycogen; polysaccharide made up of individual glucose molecules that have been dehydrated to be linked together. Clicker question 1: plants do need to carry out cellular respiration. Plants carry out cr during the day. Plants carry out photosynthesis during the day. Glucose and oxygen broken down into carbon dioxide, water, and atp energy. Electrons further from nucleus contain more energy. Carbon-hydrogen bonds are equidistant from both atomic nuclei and therefore, electrons can be easily removed; easily oxidize the molecule. Uncontrolled: lighting glucose on fire, provide activation energy and energy is released to produce carbon dioxide and water; energy is lost as heat, not available to do work. At each step, there is an opportunity to transfer the energy to carrier molecule (nadh and fadh2); high energy electron carriers used to synthesize atp; exergonic and spontaneous.
