Answer :
1. An electron carrier transports electrons and their energy to another molecule.
2. The equation of photosynthesis is 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
3. In the stroma NADPH and ATP combine with carbon dioxide to produce sugars.
4. In the thylakoid membrane, light energy from the sun splits water and generates ATP and NADPH.
5. Chloroplasts are not found in heterotrophic cells.
6. Autotrophs need light to carry out photosynthesis.
Why are the answers correct?
An electron carrier is an important molecule involved in cellular respiration as it transports electrons, along with their energy, to another molecule.
Photosynthesis is the process by which plants and organisms such as algae use energy from the sun to convert water, and carbon dioxide to produce oxygen and sugar.
The stroma uses ATP and NADPH in the next stage of photosynthesis to produce three-carbon sugars.
The thylakoid membrane contains chlorophyll and is located in the stroma where the light energy from the sun splits water and generates ATP and NADPH.
In summary, chloroplasts are organelles found in the cells of autotrophs and not heterotrophs.
