Cellular Respiration Review Flashcards
Toward the end of a marathon, a runner notices that she is getting
tired and her legs are cramping. because of?
Lactic Acid
Which of the following performs cellular respiration?
a. Plants
b. Animals
c. Humans
d. All of the above
d. All of the above
Which of the following produces ATP?
a. Fermentation
b. Photosynthesis
c. Aerobic Respiration
d. All of the above
d. All of the above
What product from the Kerbs Cycle is waste from your body?
CO2
Which of the following best describes the metabolic changes that
occur in the yeast cell?
Glycolysis will still happen. Pyruvate won’t form.
So, the yeast cell will undergo alcohol fermentation.
What is the next stage after Glycolysis if there is no oxygen available?
Fermentation
In which way are photosynthesis and cellular respiration different?
Photosynthesis uses carbon dioxide.
Cellular respiration produces carbon dioxide.
What are the products of cellular respiration?
ATP and Carbon Dioxide
What is the powerhouse of the cell?
Mitochondria
How many net ATPs are produced in the first stage?
2
What waste product is released during cellular respiration?
CO2
What is the reduced form of NAD+?
NADH
Cells produce ATP most efficiently in the presence of
Oxygen
What is the outcome of Glycolysis?
Pyruvic molecules
In the presence of oxygen, cellular respiration occurs in two stages.
They are:
Krebs — ETC
When oxygen is present, which molecule is coming from the Pyruvate?
Acetyl — CoA
Where does the Krebs cycle occur?
Mitochondria Matrix
Which organism produces its own food/glucose?
Autotrophs (plants)
Where in the cell does Glycolysis take place?
Cytoplasm
Which process produces the most ATP per molecule of glucose?
Aerobic respiration
