Study Notes
Breakdown of Substances
- The process of breaking down complex substances into simpler ones is called catabolism.
Photosynthesis
- Photosynthesis converts light energy into chemical energy, primarily in plants, using the pigment chlorophyll.
Respiration
- The primary function of respiration in living organisms is to convert biochemical energy from nutrients into adenosine triphosphate (ATP), releasing waste products.
Excretion
- The purpose of excretion is to remove metabolic waste products from the body, maintaining homeostasis and preventing toxic buildup.
Role of Chlorophyll
- Chlorophyll absorbs light energy, facilitating the conversion of solar energy into chemical energy during photosynthesis.
Cellular Respiration Organelle
- The cellular organelle primarily responsible for cellular respiration in eukaryotic cells is the mitochondrion.
ATP Function
- Adenosine triphosphate (ATP) functions as the main energy currency of cells, providing energy for various cellular processes, including muscle contraction and biochemical reactions.
Kidneys and Excretion
- In the context of excretion, the primary function of the kidneys is to filter blood, removing waste products and regulating fluid balance.
