Photosynthesis Flashcards

Flashcards about photosynthesis based on lecture notes.

What type of chemical reaction is photosynthesis?

Endothermic chemical reaction

What energy conversion occurs during photosynthesis?

Light energy is converted into chemical energy.

Write the chemical reaction of photosynthesis.

6CO2 + 6H2O + light energy > C6H12O6 + 6O2

Why is photosynthesis considered an endothermic reaction?

It stores the sun’s energy in the carbon to carbon bonds of glucose.

Where does photosynthesis take place?

In photosynthetic bacteria and organisms who have a chloroplast.

Where do the first steps of photosynthesis occur inside the chloroplast?

Within the thylakoid membrane and the chloroplast’s stroma.

Which organisms perform photosynthesis?

Autotrophic producers; photosynthetic bacteria, plants, photosynthetic protists, diatoms, plankton, and algae.

What are autotrophs?

Organisms who can harness light energy and create stored chemical energy.

What is the role of photosynthesis in energy conversion?

The first step in converting the sun’s light energy into chemical energy (glucose).

Who performs photosynthesis in the food chain?

Autotrophic producers.

Besides consumers, who else utilizes the products of photosynthesis (glucose)?

Producers use the glucose to make ATP by cellular respiration to have energy to grow, reproduce, and live.

What happens to glucose when primary consumers eat producers?

Cellular respiration breaks down the glucose molecules in order to release the energy stored in the carbon to carbon bonds.
