Your Name (Optional)

Q1 Beginner 1 pts

What is the main purpose of cellular respiration? Video Reference:
"Cellular respiration which we can describe as an exothermic reaction which transfers energy from glu..."

Timestamp: 0:30

To create energy To break down glucose To release energy from glucose To produce carbon dioxide

Q2 Intermediate 2 pts

Which type of respiration is more efficient at transferring energy from glucose? Video Reference:
"Aerobic respiration is the more common type and takes place whenever there's enough oxygen which is ..."

Timestamp: 1:30

Aerobic respiration Anaerobic respiration They are equally efficient Respiration does not transfer energy

Q3 Beginner 1 pts

What is the main byproduct of anaerobic respiration in humans? Video Reference:
"The word equation for anerobic respiration is glucose goes to form lactic acid and there are really ..."

Timestamp: 2:00

Carbon dioxide Lactic acid Ethanol Water

Q4 Intermediate 2 pts

True or false: Anaerobic respiration in plants and yeast produces ethanol and carbon dioxide. Video Reference:
"In the case of yeast we call this process fermentation and we can take advantage of it in industry f..."

Timestamp: 2:30

True

False

Q5 Intermediate 2 pts

Which of the following are examples of how organisms use the energy from respiration? (Select all that apply) Video Reference:
"One way is to build up larger molecules from lots of smaller ones for example combining amino acids ..."

Timestamp: 1:00

Select all correct answers

Building larger molecules Muscular contraction Maintaining body temperature Producing carbon dioxide

Q6 Beginner 1 pts

True or false: Aerobic respiration takes place in the mitochondria of cells. Video Reference:
"Specifically though it takes place within these subcellular structures known as mitochondria...."

Timestamp: 1:45

True

False

Q7 Advanced 3 pts

Which of the following are disadvantages of anaerobic respiration? (Select all that apply) Video Reference:
"The second problem is that it produces a lactic acid which is toxic so it has to be removed from our..."

Timestamp: 2:00

Select all correct answers

Glucose is only partially broken down It produces a toxic byproduct It is less efficient at transferring energy It requires oxygen

Q8 Advanced 3 pts

What is the main difference between aerobic and anaerobic respiration? Video Reference:
"Aerobic respiration is the more common type and takes place whenever there's enough oxygen which is ..."

Timestamp: 1:30

Aerobic requires oxygen, anaerobic does not Aerobic produces carbon dioxide, anaerobic does not Aerobic is more efficient, anaerobic is less efficient Aerobic takes place in mitochondria, anaerobic does not
