Cell Respiration
What is the "goal" of cellular respiration? Why do cells need to do it?
To create ATP
Does Glycolysis produce ATP?
Yes. Glycolysis produces a small amount of ATP
Does fermentation require oxygen?
No. Fermentation is anaerobic.
ATP is the primary source of __________ for the vast majority of cells.
Energy
How many Earths could fit in the sun?
a. 532
b. 2576
c. 238,000
d. 1.3 million
d. 1.3 million
What are the reactants (inputs) for cellular respiration?
Glucose + Oxygen
Does glycolysis require oxygen?
No. Glycolysis is anaerobic
Does fermentation produce ATP?
No. Fermentation does not produce ATP
This cell type uses ATP to operate the sodium/potassium pump, enabling it to maintain an ion gradient so that it can send messages to other cells.
Neurons
How many cells make up an average adult?
a. 40 - 45 million
b. 30 - 38 trillion
c. 12 - 20 billion
d. 700 - 800 billion
b. 30 - 38 trillion
What are the products (outputs) of cellular respiration?
CO2 + H2O + ATP
During glycolysis, NAD+ is converted into...
NADH
What molecule does fermentation produce that is needed during Glycolysis?
NAD+
This type of cell uses ATP to help it capture the sun's energy and store it as chemical energy in the form of Glucose.
Plant cell.
What percentage of your body's energy does your brain consume?
a. 10%
b. 20%
c. 30%
d. 40%
b. 20% (which is crazy, because your brain is only 2% of your body weight)
How many steps are there in cellular respiration?
3 (4, if you count pyruvate oxidation as a separate step)
What two molecules are required for glycolysis to occur?
Glucose, and NAD+
Fermentation allows glycolysis to continue running by converting _____ into ______.
(The answer does not include the terms "Pyruvate, "ethanol", or "lactate")
Converting NADH into NAD+
Despite being roughly 1000 times smaller than a human cell, this unicellular organism uses ATP for a number of tasks, including reproduction, protein synthesis, cell repair, DNA replication, and more!
Bacterium
How fast is the Earth orbiting around the Sun?
a. 66,600 mph
b. 27,000 mph
c. 10,000 mph
d. 5,000 mph
a. 66,600 mph
Which step of cellular respiration produces the majority of the cell's ATP? Does this step require oxygen?
Electron Transport Chain; yes, it requires oxygen
What 3 molecules are produced during glycolysis?
NADH, ATP, and Pyruvate
What are the two types of fermentation, and what is the difference between the two?
Lactic acid fermentation and alcohol fermentation. Lactic acid fermentation turns pyruvate into lactate whereas alcohol fermentation turns pyruvate into ethanol.
1. enables contraction by allowing myosin to interact with actin
2. enables calcium pumps to move calcium ions back into storage during muscle relaxation.
3. repair cell structures
4. replicate DNA
5. Divide the cell
Approximately how wide is the most massive black hole known to mankind?
a. approximately 5347 miles wide
b. approximately 562 thousand miles wide
c. approximately 117 million miles wide
d. approximately 121 billion miles wide
d. ~121 billion miles wide
That's more than 20 times larger than our solar system...
