Question

question 1 of 25
these images show models of a sugar molecule made during photosynthesis and an amino - acid molecule.
sugar
amino acid
which feature of the amino - acid molecule could be used to support the idea that it contains carbon atoms from a sugar molecule?
a. it has a sulfur atom between two of its carbon atoms.
b. it has a chain of carbon atoms bonded to each other.
c. it has a nitrogen atom attached to one of its carbon atoms.
d. it has fewer oxygen atoms than the sugar molecule.

Explanation:

Step1: Analyze option A

The presence of a sulfur atom between carbon - atoms doesn't relate to carbon - atom origin from sugar.

Step2: Analyze option B

Sugar molecules have carbon - carbon bonds in their structure. Amino acids having a chain of carbon atoms bonded to each other could imply that some of those carbon atoms were derived from a sugar molecule during metabolic processes as carbon - carbon bonds are a characteristic feature of sugar molecules and can be transferred during biochemical reactions.

Step3: Analyze option C

The attachment of a nitrogen atom to a carbon atom doesn't indicate carbon - atom origin from sugar.

Step4: Analyze option D

The number of oxygen atoms has no direct relation to the origin of carbon atoms in the amino - acid from a sugar molecule.

Answer:

B. It has a chain of carbon atoms bonded to each other.
