AURORKA [14]

<u>Answer</u>:

16 - light

17 - H_{2}O

18 - CO_{2}

19 - O_{2}

20 - sugar

The image describes the process of photosynthesis and the production of sugar through the Calvin cycle. Light is the energy source that drives this process through which, together with water molecules, chemical energy known as ATP is produced. This and NADPH, which is also produced during photosynthesis, are used to drive the Calvi Cycle. Here, by using atmospheric CO_{2}, sugars are produced. These are vital to the survival and growth of the plant. Oxygen is also released into the atmosphere as a result of photosynthesis.

Glycolysis is the standard way for the formation of acetyl-CoA, from glucose.

Second, beta-oxidation of fatty acids generates 2 acetyl-coA molecules per cycle.
