Study Notes
Autotrophs
- Organisms that can produce their own food through photosynthesis or chemosynthesis.
- Examples include plants, algae, and some bacteria.
- Utilize sunlight or chemical energy to convert carbon dioxide and water into glucose.
Chlorophyll
- A green pigment located in the chloroplasts of autotrophs.
- Primarily involved in capturing light energy for photosynthesis.
- Functions by absorbing light, mainly in the blue and red wavelengths.
Photosynthesis
- The process by which autotrophs convert light energy into chemical energy, stored as glucose.
- Occurs in two main stages: light-dependent reactions and the Calvin cycle.
Light-Dependent Reactions
- These occur in the thylakoid membranes of chloroplasts.
- Require light to energize electrons, resulting in the production of ATP and NADPH.
- Oxygen is released as a byproduct from water splitting.
Calvin Cycle
- Takes place in the stroma of chloroplasts.
- Utilizes ATP and NADPH produced in light-dependent reactions to convert carbon dioxide into glucose.
- Involves three main stages: carbon fixation, reduction phase, and regeneration of ribulose bisphosphate (RuBP).
Chlorophyll Reflection
- Chlorophyll a reflects green light and absorbs mainly blue and red light.
- Chlorophyll b reflects light primarily in the blue and orange-red ranges and supports chlorophyll a by capturing light energy.
End Product of Photosynthesis
- The primary end product is glucose, which serves as an energy source for the plant and other organisms that consume it.
