Revise: Photosynthetic ReactionPhotosynthesis is an endothermic reaction. This means it takes in energy from its surroundings rather than releasing energy to them. Energy is transferred from the environment to the chloroplasts by light, usually sunlight.
- Revise: Exothermic and Endothermic Reactions: Energy Transfers and Uses
A chemical reaction that takes in energy from the surroundings, causing their temperature to decrease.
- Revise: Reaction Profiles
A chemical reaction that takes in energy from the surroundings; its products have more energy than its reactants.
