A seed respires tripalmitin only.
- What is the respiratory quotient?
- The seed takes in mL of oxygen. What volume of carbon dioxide does it release?
Need a reminder? The key ideaShow
. It is for carbohydrate, about for protein, for fat, and above for organic acids. KOH takes in carbon dioxide, so the fall of volume in a tube with KOH is the oxygen taken in.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Given. The equation, and mL of oxygen.
Plan. Find the ratio, then use it for the volume.
Step 1. RQ. .
Step 2. Carbon dioxide. mL.
Answer: ; mL.
Check. . The carbon dioxide is smaller than the oxygen, as it should be for a fat.
