Question

question 8 0.75 pts students will be measuring both o2 and co2 production in two different situations. in the space below, make your predictions as to the production of o2 and co2. the predictions should be in complete sentences and clearly labeled. example: #1- i predict the the amount of oxygen in the chamber containing the yeast will____ 1. predict what will happen to the amount of o2 in the chamber containing active yeast at room temperature after 600 seconds? (hint- will it increase or decrease?) 2. predict what will happen to the amount of co2 in the chamber containing active yeast at room temperature after 600 seconds? 3. predict what will happen to the amount of o2 in the chamber containing dormant yeast at room temperature after 600 seconds? 4. predict what will happen to the amount of co2 in the chamber containing dormant yeast at room temperature after 600 seconds?

Explanation:

1. Active yeast undergoes cellular respiration. It consumes oxygen for aerobic respiration, so the amount of O₂ will decrease.
2. As a by - product of cellular respiration, active yeast produces CO₂, so the amount of CO₂ will increase.
3. Dormant yeast has very low metabolic activity. It will consume little to no oxygen, so the amount of O₂ will remain relatively stable.
4. Due to low metabolic activity, dormant yeast will produce little to no CO₂, so the amount of CO₂ will remain relatively stable.

Answer:

1. I predict the amount of O₂ in the chamber containing active yeast at room temperature after 600 seconds will decrease.
2. I predict the amount of CO₂ in the chamber containing active yeast at room temperature after 600 seconds will increase.
3. I predict the amount of O₂ in the chamber containing dormant yeast at room temperature after 600 seconds will remain relatively stable.
4. I predict the amount of CO₂ in the chamber containing dormant yeast at room temperature after 600 seconds will remain relatively stable.
