What are the functions of a typical eukaryotic cell? | Movement, conduction, metabolic absorption, secretion, excretion, respiration, reproduction, and communication. |
What are the functions of the nucleus? | Cellular division, control of genetic information, replication and repair of DNA and transcription of the information stored in the DNA. |
Identify the cytoplasmic organelles. | Ribosomes, Endoplasmic reticulum, Golgi complex, Lysosomes, Peroxisomes, Mitochondria, Cytoskeleton, Caveolae, and Vaults. |
What is the structure of the plasma membrane bilayer? | A bilayer of phospholipids, glyolipids, and cholesterol. Each molecule is amphipathic, meaning that one part of the molecule is hydrophobic, and the other is hydrophilic,resulting in automatic self orientation of the cell membrane. |
What is the function of proteins in the lipid bilayer? | Classified is integral or peripheral membrane proteins. They function as: receptors, pores or transport channels, enzymes to drive ion pumps, surface markers, cell adhesion molecules (CAMs), and catalysts of chemical reactions. |
What are the primary modes of chemical signaling? | - Hormonal - Paracrine - Autocine - Neurotransmitters - Neurohormone section |
