Cell Structure and Function
- Endoplasmic Reticulum (ER): Involved in protein synthesis, lipid synthesis and modification. Two types: rough (with ribosomes) and smooth (agranular).
- Golgi Apparatus: Processes substances from the ER, modifies and packages them into lysosomes, secretory vesicles, other cellular components.
- Lysosomes: Contain digestive enzymes, break down intracellular substances (damaged cells, food particles, bacteria). Membranes protect them from damaging cell contents.
- Mitochondria: Release energy via oxidation of foods (carbohydrates, fats, proteins). Crucial for ATP formation from ADP.
- ATP Formation: Main pathway occurs in the mitochondria: foods are broken down, hydrogen ions combine with oxygen (releasing energy), energy used to convert ADP to ATP. Process called the chemiosmotic mechanism.
- ATP Usage: ATP fuels cellular processes; membrane transport (sodium-potassium pump), synthesis, and mechanical work (muscle contraction).
- Cilia: Whiplike structures, involved in movement of mucus (respiratory system), and fluid (uterine tubes). Require ATP and specific ionic conditions (magnesium, calcium).
Genetic Control of Protein Synthesis
- Gene Function: Genes (DNA) control protein synthesis and therefore cell function via the process of gene expression.
- DNA Structure: Double-stranded helix composed of nucleotides with phosphoric acid, deoxyribose sugar, nitrogenous bases.
- DNA Code: Organized as triplets of bases forming code words. A unique code word determines the sequence of amino acids in the resultant protein.
- Transcription: Process where DNA code is copied to RNA code (which moves to the cytoplasm). RNA needs proteins and proper ionic environment for the synthesis.
- Figure 3–1: Demonstrates the process by which genes in the nucleus control cell function in the cytoplasm. RNA is transcribed from the DNA and translated to proteins in the cytoplasm.
