Hesi Exam Biology 2

second half of questions

QuestionAnswer
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.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
