Study Notes
ATP Production
- Mitochondria are the key organelles responsible for producing adenosine triphosphate (ATP), the main energy currency of the cell.
- They carry out cellular respiration, converting glucose and oxygen into ATP while releasing carbon dioxide and water.
Loose Connective Tissue
- Loose connective tissue provides support and flexibility, acting as a filler between organs and tissues.
- It contains more ground substance than fibers, allowing for cushioning and diffusion of nutrients and waste.
Endoplasmic Reticulum (ER)
- The endoplasmic reticulum is vital for protein and lipid synthesis within a cell.
- There are two types: Rough ER, studded with ribosomes for protein production, and Smooth ER, involved in lipid synthesis and detoxification.
Cell Structure Support
- The cytoskeleton is the structure that maintains cell shape, offers mechanical support, and facilitates cellular movement.
- It consists of microfilaments, intermediate filaments, and microtubules, each serving distinct roles in maintaining integrity and enabling mobility.
Epithelial Tissue
- Epithelial tissue lines the outer surfaces of organs and blood vessels and the inner cavities of glands.
- It functions in protection, absorption, secretion, and sensation, forming critical interfaces between the body and environment.
Protein Synthesis
- Ribosomes are the organelles responsible for synthesizing proteins in cells.
- They can be found floating freely in the cytoplasm or attached to the rough endoplasmic reticulum, translating messenger RNA into polypeptide chains.
