3 protein bars were tested to see which of them had the highest amount of carbohydrates. Bar A has an RQ of .65, Bar B has an RQ of 9, and Bar C has an RQ of 4.5. a. Which bar contains more carbohydrate molecules?

b. Explain how you know.

The correct answer is -

a) Bar B with RQ of 9 contains more carbohydrates.

b) The higher the RQ value above RQ = 1, the higher amount of carbohydrates present.

Explanation:

The respiratory quotient or RQ is the representation of the particular metabolized nutrient as lipids, carbohydrates and protein uses different energy pathways and releases a different number of oxygen molecules. It is a basal metabolic rate when estimated from carbon dioxide production.

In the case of protein metabolism, the RQ value is approximately 0.8, for lipids, it is approximately 0.7, and for carbohydrates, it is 1.0. The higher the RQ value above RQ = 1, the higher amount of carbohydrates present.

An RQ of >1.0 suggests excessive carbohydrate provision. And the given case the bar B has a maximum RQ value that is 9.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
