Study Notes
Function of Mitochondria
- Mitochondria are responsible for cellular respiration, the process of converting nutrients into energy
- They are often referred to as the "powerhouses" of the cell
- This energy is stored in the form of ATP (adenosine triphosphate) which is used by the cell to perform various functions
Role of Enzymes
- Enzymes are biological catalysts that accelerate the rate of chemical reactions within a cell
- They do this by lowering the activation energy required for reactions to occur
- They are specific to certain reactions and are essential for many biological processes
Cell Membrane Regulation
- The cell membrane, also known as the plasma membrane, regulates what enters and exits the cell.
- It is selectively permeable, meaning it allows some substances to pass through while blocking others
- This regulation maintains the internal environment of the cell and allows for the exchange of nutrients and waste products
Phenotype
- Phenotype refers to the observable physical or biochemical characteristics of an organism
- It is determined by the interaction of an organism's genotype (genetic makeup) with the environment
- Examples of phenotypes include eye color, height, and disease susceptibility.
Chloroplast Function
- Chloroplasts are organelles found in plant cells that are responsible for photosynthesis
- Photosynthesis is the process by which plants convert light energy from the sun into chemical energy in the form of glucose
- This process uses carbon dioxide and water as reactants and releases oxygen as a byproduct
