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
, 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
