Question

What kind of energy transformation takes place when plants perform photosynthesis to produce glucose molecules

Answer 1

Answer: Light energy to chemical energy

Step-by-step explanation:

Photosynthesis comes from the words photo which means light and synthesis which means to make. Thus, plants use sunlight to make food.

In photosynthesis, carbon dioxide and water react in the presence of sunlight and chlorophyll to produce glucose molecules and oxygen.

Thus, light energy is transformed to chemical energy which is stored in glucose molecules formed.

This is consumed as food by consumers and they get energy by burning this and then chemical energy stored in these molecules converts into mechanical energy and heat.

Answer 2

So the energy transformations are: Light - Electrical - Chemical Explanation Chloroplast contain molecules called PSI and PSII and other light harvesting molecules, which upon excitation by light from sunlight, in the form of photon, release electrons. These excited electrons then passes through series of proteins in order to form ATP and NADPH and causes the breakdown of water molecule (photolysis due to light) and releases 1 molecule of oxygen. This process is called Light reaction. The energy produced from ATP and NADPH is consumed in light-independent pathway (Dark reaction), for fixing carbon dioxide into glucose by the most abundant enzyme, RUBISCO.
