Study Notes
Mitochondria Function
- The primary function of mitochondria is to produce energy for the cell through cellular respiration.
- Mitochondria are responsible for the breakdown of glucose molecules to generate ATP (adenosine triphosphate), which is the primary energy currency of cells.
Cell Membrane Structure
- Phospholipids are the primary macromolecule responsible for the structure of cell membranes.
- Phospholipids have a unique structure with both hydrophilic (water-loving) and hydrophobic (water-fearing) regions, allowing them to form a selectively permeable membrane.
Protein Synthesis
- The process of protein synthesis involves the assembly of amino acids into polypeptide chains.
- This process occurs in two main steps: transcription and translation.
Enzyme Function
- Enzymes are biological catalysts that speed up chemical reactions in living organisms.
- Enzymes lower the activation energy of a reaction, allowing it to proceed at a faster rate.
- They are highly specific, typically catalyzing only one or a small number of reactions.
Cellular Respiration
- The primary purpose of cellular respiration is to generate energy in the form of ATP.
- This process involves the breakdown of glucose, a simple sugar, in the presence of oxygen to produce ATP, carbon dioxide, and water.
