What are the two major classes of living cells? - ANSWER Prokaryotes and Eukaryotes What is a Prokaryote cell? - ANSWER Characterized by a LACK of distinct nucleus.What are examples of Prokaryotes? - ANSWER Cyanbacteria, Bacteria, and Rickettsiae.What is a Eukaryote cell? - ANSWER Cells WITH A WELL- DEFINED NUCLEUS and membrane bound organelles.What are examples of Eukaroytes? - ANSWER Higher animals, Plants, Fungi, and Protozoa. 1 / 4
What are the cellular functions? - ANSWER movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction, communication.What are the three general components of Eukaroytes? - ANSWER Plasma Membrane, Cytoplasma, and Intracellular organelles.What is the function of the nucleus in Eukaryotic cells? - ANSWER Cell division and control of genetic information.What is the function of the cytoplamsa in Eukaroytic cell? - ANSWER
EGG WHITE
Fills the space between the nucleus and cell membrane.Transports waste, metabolic processes, motility, and storage.Function of the Ribsomes in Eukaryotic cell? - ANSWER Synthesizes proteins and signaling.Function of the endoplasmic reticulum in Eukaroytic cell? - ANSWER Protein synthesis and senses cellular stress.Function of the Mitochondria in Eukaroytic cell? - ANSWER Power stations that produce energy. 2 / 4
Function of the golgi complex in Eukaroytic cell? - ANSWER Refining plant Directs traffic especially transports proteins in and out of the cell.Function of lysomes in Eukaroytic cell? - ANSWER PAC MAN Eat anything in front of it, digestion, and nutrient signaling.What are peroxisomes? (Cellular parts) - ANSWER Major sites of oxygen utilization and help nerve myelination.What is the Cytsol? (Cellular Parts) - ANSWER 55% cell volume, storage, and metabolizes enzymes.What is the cytoskeleto? (Cell parts) - ANSWER The bones and muscles of the cell. Maintains cell shape, movement in and around cell.What is the plamsa membrane? (Cell Parts) - ANSWER Encases the cell, has transport systems, cell to cell recognition, and allows lipids to leave and transport things on hormones.Which cell has a polar end and non-polar end? - ANSWER Eukaryotic cells.Membrane composition of Eukaroytic cells/higher cells? - ANSWER Made up of PROTEINS. 3 / 4
Made from a chain of amino acids known as POLYPEPTIDES."WORKHORSES" of the cell.Functions: Receptors, transporters, enzymes, surface markers, adhesion molecules, and catalysts.What is the proteolytic cascade with Eukaroytic cells? - ANSWER How proteins breakdown and move.Tightly orchestrated sequence of events that cause the breakdown of protein.What is Apoptosis with Eukaroytic cells? - ANSWER Pre-programmed cell death.Every cell has an expiration date.RBCs 90 day expiration.What are the cellular receptors with Eukaroytic cells? - ANSWER Protein molecules on the plasma membrane, in cytoplasma, or in nucleus.
Plasma membrane receptors: Make availability for membranes (EGG CARTON)
Ligands: (BROKEN EGG STUCK IN CARTON): determine how cells bind or signals not to bind in surface or cell.What are the three mechanisms that bind cells together? - ANSWER Extracellular matrix, cell adhesion cells, and specialized cell junctions.What is the extracellular matrix and what are examples? - ANSWER Mesh of fibrous proteins: fibroblasts, hyaluronic acid, collagen (watery gel-like substance in complex carbs.
