Question | Answer |
---|---|
Active Transport | Requires ATP (energy) for transport. (transport pumps, endocytosis, exocytosis) |
Cell Cycle | sequence of events from one division to the next. (TWO phases) |
Cell Membrane | Plasma membrane. separates intracellular from extracellular. |
Cells | Structural & functional unit of ALL living matter. |
Cytoplasm | Gel like substance,inside cell. (outside nucleus) |
Differentiate | process that causes cell to become specialized. |
Diffusion | Most common transport. (HIGHER concentration to LOWER) |
Endocytosis | Intake of food/liquid by the cell membrane. (too large for diffusion) (2 types PHAGocytsis & PINocytosis) |
Endoplasmic Reticulum (ER) | in cytoplasm. (2 types Rough [RER] & Smooth [SER]) |
Equilibrium | No further net diffusion. (equal balance) |
Exocytosis | Moves substances OUT of cell. |
Facilitated diffusion | A passive transport. (Substance HELPED across cell membrane by a molecule within membrane.) |
Filtration | Substances is PUSHED across (in/out)of the cell membrane by pressure. (a syringe) |
Golgi Apparatus | Finishing touches on protein that were received by Rough ER.(pinches off sac to release protein.) |
Lysosomes | Contains powerful enzymes. (Digestive organelles)["CLEAN HOUSE" like LYSOL cleaning products] |
Mitochondria | "POWER PLANTS" Produce MOST of the energy the cell requires. (Two layers Outer layer smooth & inner layer called Cristae) |
Mitosis | (1 of 2 types of)Cell Division. Splitting of 1 cell into 2 daughter cells. [Making "IDENTICAL" cells] |
Nucleus | The control center of the entire cell. (contains genetic info. & controls ALL protein synthesis) |
Organelle | Each organelle have a specific role.("little organs") |
Osmosis | Diffusion of WATER. (From HIGHER concentration to a LOWER) |
Passive Transport | Requires NO additional ATP. |
Ribosomes | Organelles. Protein synthesis. (Some attached to RER others float around in cytoplasma) |
Phagocytosis | Cell is EATING. (a solid particle) |
Pinocytosis | Cell is DRINKING. ((a water droplet) |
Rough Endoplasmic Reticulum | Protein synthesis. (Ribosomes on outside surface. sandpaper-like appearance)when done it is passed to golgi apparatus. |
Smooth Endoplasmic Reticulum | Steroids & Lipids synthesis. (No ribosomes) |
Aerobic catabolism | Needs O2 to breakdown glucose. |
Amino acids | Building blocks for protein. (about 20 amino acids) |
Anabolism | building up to larger (complex) substances. (ex. amino acids) |
Anaerobic catabolism | Does NOT need O2 to breakdown glucose. (two steps pyruvic acid then to lactic acid) |
Base-pairing | Adenine/Thymine & Cytosine/Guanine |
Base-sequencing | list of bases (GAC/CAA) |
Carbohydrates | Organic compounds. (has C, H & O2) (classified Monosaccharides, Disaccharides, Polysaccharides) |
Catabolism | Breaking down of large complex substances. |
Deoxyribonucleic acid (DNA) | |
Glucose | Used for cell energy. (Most important) |
Gluconeogenesis | |
Glycogen | |
Glycolysis | |
Lipid | |
Metabolism | A series of chemical reactions to use raw materials. (2 types anabolism & catabolism) |
Monosaccharides | Single sugar compound. [includes a 6 carbon molecule = glucose, also includes fructose & galactose] |
Peptides bond | |
Proteins | most abundant organic matter in the body. (include enzymes, most hormones, hemoglobin & contractile proteins) |
Ribonucleic acid (RNA) |
