Anaerobic - -Process does not utilize oxygen
-Aerobic - -Utilizes oxygen
-Where does glycolysis occur? - -Cytoplasm
-What are the inputs of glycolysis? - -2 ATP, glucose, 2 NAD+
-What are the outputs of glycolysis? - -4 ATP, pyruvate, 2 NADH
-What is the net gain of glycolysis? - -2 ATP, 2 NADH
-Cellular Respiration equation - -Glucose (C6+H12+06) + Oxygen (O2)------> Carbon
Dioxide (CO2) + Water (H2O) + ATP
-Where does the Citric Acid Cycle take place? - -Matrix of the Mitochondria
-How many times does the Citric Acid Cycle turn? - -2
-Prep Stage equation - -2 Pyruvate ----> Acetyl COA, CO2, 2 ATP, 2 NADH
-Oxidization - -Loses electrons
-Citric Acid Cycle input - -2 Acetyl Groups, 6 NAD+, 2 FAD, 2 ADP+2P
-Citric Acid Cycle output - -4 CO2, 6NADH,2 FAD2, 2ATP
-Electron Transport Chain input - -10 NADH, 2 FAD
-Electron Transport Chain output - -10 NAD+, 2 FAD, 32-34 ATP
-Net Gain for Cellular Respiration - -36-38 ATP
-Where does the Electron Transport Chain take place? - -Cristae of the mitochondria
-Steps of the Electron Transport Chain - -1)H+ can't enter the chain, follow chain e-
2)H+ reaches ATP synthase and gets pumped through the electron transport chain
3) Electrons + hydrogen are picked up by O2 ------> H2O produce CO2
-Chemiosmosis - -Movement of hydrogen ions across the cristae during ATP production
-ATP synthase - -Enzyme that creates ATP
, -Homeostasis - -Constant internal environment
-Why is the plasma membrane called "Fluid-Mosaic"? - -The membrane and its proteins
able to shift back and forth because it isn't completely solid nor liquid
-Which type of protein in the plasma membrane has carbohydrates attached to it so that
cells can be recognized from each other? - -Cell-Recognition Proteins
-Which protein allows a particular molecule or ion to freely cross the plasma membrane as
it enters or exits the cell? - -Channel Protein
-Which protein combines with a substance and helps to move it across the membrane? - -
Carrier Protein
-Which protein has a specific shape such that only a particular molecule can bind to it? - -
Receptor Protein
-Which protein transports sodium and potassium ions across the cell membrane? - -
Carrier Protein
-In the sodium-potassium pump, what goes in the cell and what exits the cell? - -Potassium
is carried in, sodium is carried out
-Which protein carries out metabolic reactions? - -Enzymatic Proteins
-How is the plasma membrane selectively permeable? - -Only certain substances can cross
(small, noncharged molecules)
-What cannot pass through the plasma membrane? - -Ions, charged molecules, large
molegules
-Diffusion - -Movement of molecules from a high concentration to a low concentration
-Facilitated Diffusion - -Passive transport that uses the membrane proteins to help larger,
charged molecules pass throught the gradient
-Simple Diffusion - -Passive transport where the molecules pass through the plasma
membrane (or spread) without the use of proteins
-Osmosis - -The diffusion of water across a selectively permeable membrane
-Hypotonic Solution - -Cause the cell to swell because of the intake of water
-Hypertonic Soluton - -Cause the cell to shrivel because of the flow of water out of the cell
-Isotonic Solution - -The solute and water concentration are equal
