Hesi Exam Biology 2
second half of questions
| Question | Answer |
|---|---|
| metabolism | sum of all chemical reaction that occur in an organism |
| metabolic pathways | goes from high energy to low energy in a cell |
| metabolism | all reaction are catalyzed by the use of enzymes |
| Prokaryotic Cell | no defined nucleus |
| Eurkaryotic Cell | membrane enclosed nucleus |
| Prokaryotic Cell | carries out functions of the cell as ordered by the nucleus, no organelles |
| Eurkaryotic Cell | series of organelles that carry out functions of the cell as directed by the nucleus |
| Nucleus | contains chromosomes |
| Nucleus | contains all material for regeneration of the cell |
| Nucleus | contains all of the instructions for the cell |
| Ribrosomes | read the RNA |
| ribrosomes | translates genetic instructions to produce proteins |
| Bound Ribrosomes | found in er(endoplasmic reticulum |
| Free Ribrosomes | found in cytoplasm |
| Endoplasmic Reticulum | attatched to the nuclear membrane |
| Rough ER | responsible for protein synthesis and membrane production |
| Smooth ER | funcitons in detoxification and metabolism |
| Golgi Apparatus | packaging, processing, and shipping organelle |
| Golgi apparatus | transports material farom the Er througout the cell |
| Lysosomes | Intracellular digestion takes place here |
| Lysosomes | Packed with hydrolytic enzymes |
| Lysosomes | Can Hyrolyze proteins, fats, sugars, and nucleic acids |
| Vacoules | membrane enclosed |
| Phagocytosis | uptake food through the cell membrane creating a food Vacoule |
| Central Vacoule | In a plant and functions as storage, waste, disposal, protection, and hydrolysis |
| Mitochondria | located in Eukaryotic cells |
| chloraplasts | Located in plants |
| Mitochondria | site for respiration |
| Chloroplasts | Site for photosynthesis |
| Cellular Membrane | most important componant of the cell |
| ATP | used as currency of the cell |
| Cellular membrane | has bilayer of phosolipids with proteins, cholesterol, and glycoproteins peppered throughout |
| ATP | Adenosine Triphosphate |
| Cellular Membrane | Bilayer creates huydrophobic layer between(region)2 layeres of lipids(selectively preamble) |
| NADH | ACTS AS REDUCING AGENT |
| Cellular Membrane | Contributes to protection, communication, and passage of substances in and out of the cell |
| NADH | Vehicle of stored energy |
| NADH | Precursor to produce greater amounts of ATP in final steps of respiration |
| Cellular Respiration1 | 1.Glycolysis, 2. Krebs Cycle, 3. Electron transport chain |
| Glycolysis | when conversion of glucose to pyruvate |
| Krebs Cycle | Pyruvate transported into the mitochondrion |
| Glycolysis | takes place in cytosol of cell |
| Krebs Cycle | takes place in the matrix of the mitochondrion |
| Electron Transport Chain | Oxidation of NADH molecules to produce oxygen and finally produce water |
| Electron Transport Chain | for every glucose molecule 28- 32 ATP can be produced |
| Glycolysis | Produces 2 molceules of atp, 2 molecules of pyruvate, and 2 molecules of NADH |
| Krebs Cycle | for 1 consumed glucose molecule, 2 atp molecules, 6 carbondioxide, molecules and 6NADH molecueles are produced |
| Photosynthesis | Light reactions, and Calvin Cycle are the two stages of this |
| Calvin Cycle | sugar produced is polymerized and stored as a polymer of glucose |
| Calvin Cycle | second stage of photosynthesis |
| Light reaction | 1st stage of photosynthesis |
| Light Reaction | converts solar energy to chemical energy |
| Light Reaction | Accomplishes production of ATP by absorbing light and using that energy to split a water molecule and transfer the electron creating NADH and producing ATP |
| Asexual Reproduction | involves Bacterial Cells |
| Asexual Reproduction | chromosomes bind to plasma membrane where it replicates |
| Asexual Reproduction | As it grows it pinches into 2, creating 2 identical cells. |
