Anaerobic - ANSWER-Process does not utilize oxygen
Aerobic - ANSWER-Utilizes oxygen
Where does glycolysis occur? - ANSWER-Cytoplasm
What are the inputs of glycolysis? - ANSWER-2 ATP, glucose, 2 NAD+
What are the outputs of glycolysis? - ANSWER-4 ATP, pyruvate, 2 NADH
What is the net gain of glycolysis? - ANSWER-2 ATP, 2 NADH
Cellular Respiration equation - ANSWER-Glucose (C6+H12+06) + Oxygen (O2)-----
-> Carbon Dioxide (CO2) + Water (H2O) + ATP
Where does the Citric Acid Cycle take place? - ANSWER-Matrix of the Mitochondria
How many times does the Citric Acid Cycle turn? - ANSWER-2
Prep Stage equation - ANSWER-2 Pyruvate ----> Acetyl COA, CO2, 2 ATP, 2 NADH
Oxidization - ANSWER-Loses electrons
Citric Acid Cycle input - ANSWER-2 Acetyl Groups, 6 NAD+, 2 FAD, 2 ADP+2P
Citric Acid Cycle output - ANSWER-4 CO2, 6NADH,2 FAD2, 2ATP
Electron Transport Chain input - ANSWER-10 NADH, 2 FAD
Electron Transport Chain output - ANSWER-10 NAD+, 2 FAD, 32-34 ATP
Net Gain for Cellular Respiration - ANSWER-36-38 ATP
Where does the Electron Transport Chain take place? - ANSWER-Cristae of the
mitochondria
Steps of the Electron Transport Chain - ANSWER-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 - ANSWER-Movement of hydrogen ions across the cristae during ATP
, production
ATP synthase - ANSWER-Enzyme that creates ATP
Homeostasis - ANSWER-Constant internal environment
Why is the plasma membrane called "Fluid-Mosaic"? - ANSWER-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? - ANSWER-Cell-Recognition Proteins
Which protein allows a particular molecule or ion to freely cross the plasma
membrane as it enters or exits the cell? - ANSWER-Channel Protein
Which protein combines with a substance and helps to move it across the
membrane? - ANSWER-Carrier Protein
Which protein has a specific shape such that only a particular molecule can bind to
it? - ANSWER-Receptor Protein
Which protein transports sodium and potassium ions across the cell membrane? -
ANSWER-Carrier Protein
In the sodium-potassium pump, what goes in the cell and what exits the cell? -
ANSWER-Potassium is carried in, sodium is carried out
Which protein carries out metabolic reactions? - ANSWER-Enzymatic Proteins
How is the plasma membrane selectively permeable? - ANSWER-Only certain
substances can cross (small, noncharged molecules)
What cannot pass through the plasma membrane? - ANSWER-Ions, charged
molecules, large molegules
Diffusion - ANSWER-Movement of molecules from a high concentration to a low
concentration
Facilitated Diffusion - ANSWER-Passive transport that uses the membrane proteins
to help larger, charged molecules pass throught the gradient
Simple Diffusion - ANSWER-Passive transport where the molecules pass through
the plasma membrane (or spread) without the use of proteins
Osmosis - ANSWER-The diffusion of water across a selectively permeable
membrane
Hypotonic Solution - ANSWER-Cause the cell to swell because of the intake of water
