Carbon dioxide (CO2) is incorporated into a preexisting sugar molecule.
Explanation:
Photosynthesis is a metabolic process undergone by the cells of autotrophic organisms in order to synthesize their own food. The photosynthetic process occurs I two stages viz: light-dependent stage and light-independent stage. The light dependent stage produces the energy (ATP) and reducing agent (NADPH) needed for the second stage.
The light-independent stage, also called Calvin Cycle, is the second stage of the photosynthetic process. The Calvin cycle is the stage where the glucose sugar (food) is synthesized. The very first phase of the Calvin cycle involves the fixation of Carbondioxide (CO2) by a CO2 acceptor called Ribulosbiphosphate (RUBP), as catalyzed by RUBISCO.
Hence, Carbon dioxide (CO2) is incorporated into a preexisting sugar molecule represents the event that form part of the Calvin cycle. Other options are part of the light stage.
The fossil record, however, is quite incomplete. Here's one major reason why: Sediment has to cover an organism's remains in order for the long fossilization process to begin. Most organisms decompose before this can happen.
Animals store most of their excess energy reserves as fat and this is explained because animals stores fat as a energy giving product and it keeps our body warm in winter
Answer: When a cat drops from a tree to the ground, the conversion of gravitational potential energy to kinetic energy takes place. Then runs up behind a mouse to obtain its food. After eating its prey, the conversion of chemical energy to mechanical energy takes place inside the cat's body.
