Cellular Respiration Flashcards
(27 cards)
During glycolysis, glucose is broken down into what 3 carbon compound?
Pyruvic Acid
During the electron transport chain what is pumped from the matrix across the cristae membrane into the inner membrane space?
Hydrogen protons
What molecule is the primary fuel for cellular respiration
Glucose
What type of respiration can only occur in the presence of oxygen
Aerobic respiration
In what part of the mitochondria does the Kreb’s cycle occur
Matrix
What molecule serves as a source of immediate energy for cellular processes that require energy
Adenosine Triphosphate
ATP is generated when hydrogen protons cause a rotor to spin as they flow across the cristae membrane through this enzyme
ATP synthase
At the end of the electron transport chain, low-energy hydrogen electrons and hydrogen protons are combined with oxygen to form this end product
Water
What is the nitrogen base that is found in molecules of ADP and ATP
Adenine
The energy transformation that converts the energy held in molecules of glucose to molecules of ATP is called?
Respiration
What molecule serves as the final electron acceptor in the electron transport chain
Oxygen
In the absence of oxygen, muscle cells may convert pyruvic acid into what compound
Lactic acid
What stage of cellular respiration produces hydrogen atoms, ATP, and carbon dioxide
Kreb’s Cycle
What type of fermentation produces carbon dioxide which causes bread dough to ride
Alcoholic
The addition or removal of what molecule determines whether energy is stored or released
Phosphate
In what stage of respiration does glucose convert to pyruvic acid
Glycolysis
Acetate is joined with oxaloacetic acid to form what 6-carbon compound?
Citric Acid
A large number of high energy hydrogen electrons are delivered to the electron transport chain in this form
NADH
The energy generation from what process is used to pump hydrogen protons across a membrane, generating a high concentration proton gradient
Electron Transport Chain
This folding and looping membrane increases the surface area for cellular respiration
Cristae
What is the cellular organelle where aerobic respiration takes place
Mitochondria
During the oxidation, or break down, of pyruvic acid, what compounds is given off as a waste product
Carbon Dioxide
What type of respiration occurs in the absence of oxygen
Fermentation
Anaerobic respiration takes place in this part of the cell
Cytoplasm
