Study Notes
Cell Membrane Functions
- Acts as a protective barrier, regulating the entry and exit of substances in and out of the cell.
- Maintains homeostasis by controlling the internal environment and responding to changes in the external environment.
- Contains proteins that facilitate communication, signaling, and transport across the membrane.
ATP Production
- Mitochondria are the organelles responsible for the production of ATP (adenosine triphosphate).
- ATP is generated through cellular respiration, which includes glycolysis, the Krebs cycle, and oxidative phosphorylation.
- Mitochondria are often referred to as the "powerhouses" of the cell due to their role in energy metabolism.
Genetic Information Transmission
- The process of DNA replication, transcription, and translation is essential for the transmission of genetic information.
- DNA serves as the template for RNA synthesis, which then guides protein synthesis.
- These processes ensure that genetic information is accurately passed on during cell division and throughout an organism’s development.
Basic Unit of Life
- The cell is the basic unit of life in all living organisms.
- Cells can exist as single-celled organisms (like bacteria) or as part of multicellular organisms (like plants and animals).
- All cellular functions are carried out within cells, from metabolism to growth and reproduction.
Amino Acid Bonds
- Peptide bonds are formed between amino acids in a protein.
- These covalent bonds link the carboxyl group of one amino acid to the amino group of another, releasing water in the process (condensation reaction).
- The sequence and structure of amino acids determine the protein's function and properties.
