Biology Chapter: Photosynthesis and Respiration

What is produced during photosynthesis?

In which cell organelle does photosynthesis occur?

What role does chlorophyll play in the process of photosynthesis?

What is the main product of cellular respiration?

Which of the following is a reactant in cellular respiration?

What pigment is responsible for capturing light energy in plants?

What is the Rf value in chromatography?

Which of the following statements is true regarding chlorophyll?

Photosynthesis

Plants, algae, and some bacteria use chlorophyll in chloroplasts to capture sunlight energy
This energy converts carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6), a form of stored chemical energy
Oxygen (O2) is a byproduct of this process

Cellular Respiration

Cells use cellular respiration to break down glucose using oxygen in mitochondria
This process releases energy, storing it in adenosine triphosphate (ATP) molecules
ATP powers cell activities

Photosynthesis and Cellular Respiration: Reactants and Products

Photosynthesis:
- Reactants: Carbon dioxide (CO2), water (H2O), and sunlight
- Products: Glucose (C6H12O6) and oxygen (O2)
- Location: Chloroplasts (specifically thylakoids and stroma)
Cellular Respiration:
- Reactants: Glucose (C6H12O6) and oxygen (O2)
- Products: Carbon dioxide (CO2), water (H2O), and ATP
- Location: Cytoplasm (glycolysis) and mitochondria (Krebs Cycle, Electron Transport Chain)

Chlorophyll's Function

Chlorophyll is a green pigment found in chloroplasts of plant cells
It absorbs sunlight, particularly red and blue light, converting it into energy that drives photosynthesis
Without chlorophyll, photosynthesis would not occur
