Study Notes
Cell Membrane Function
- Regulates the passage of substances in and out of the cell, acting as a selective barrier.
Protein Synthesis
- Ribosomes are essential for protein synthesis. They are responsible for translating genetic information carried by messenger RNA (mRNA) into proteins.
Enzyme Function
- Enzymes act as biological catalysts, accelerating biochemical reactions by lowering activation energy.
Cytoskeleton Functions
- The cytoskeleton is responsible for providing structural support, maintaining cell shape, and facilitating cell movement. It is NOT involved in protein synthesis.
Mitochondria Function
- Mitochondria are responsible for generating energy in the form of ATP (adenosine triphosphate) through cellular respiration. This process utilizes glucose and oxygen to produce energy.
