Clothespin Lab

Which part of the graph is showing ANAEROBIC respiration?

• The first part

• The second part

During which trial does the activity switch to AEROBIC respiration?

• Trial 1

• Trial 2

• Trial 3

• Trial 4

Describe how your hand and fingers felt near the end of your trials. Why did this occur? What waste product of cellular respiration is causing your hand to feel this way?

• alcohol

• carbon dioxide

• lactic acid

• oxygen

What type of metabolic activity was occurring at the beginning of your lab (when you were squeezing fast)?

• alcoholic fermentation

• lactic acid fermentation

• aerobic respiration

Why does your body use lactic acid fermentation when you are sprinting, lifting heavy objects, or squeezing a clothespin at full speed?

• in order to get swoll

• in order to make lactic acid

• in order to cause pain

• in order to make a small amount of ATP despite not having oxygen available

Fermentation is Cellular Respiration without which molecule?

• CO₂

• O₂

• H₂O

• C₆H₁₂O₆

Which organisms do Lactic Acid Fermentation? You may choose more than one.

• bacteria

• humans

• animals

Lactic Acid Fermentation only involves Glycolysis and then it cannot proceed further due to lack of oxygen. How many ATP do you think lactic acid fermentation produces?

• 0 ATP

• 2 ATP

• 38 ATP

• 467 ATP
