Question

complete the table to compare the structures of a protein and a carbohydrate.
table with header row (blue) and three data rows:

• row 1: may have multiple polypeptide chains | protein (circle) | carbohydrate (circle)
• row 2: has primary, secondary, and tertiary structures | protein (circle) | carbohydrate (circle)
• row 3: may have an alpha helix or a beta sheet | protein (circle) | carbohydrate (circle)
• green \submit\ button below the table

Explanation:

To solve this, we analyze the structural features of proteins and carbohydrates:

1. May have multiple polypeptide chains

• Proteins: Can have multiple polypeptide chains (e.g., quaternary structure in hemoglobin).
• Carbohydrates: Do not have polypeptide chains (they are made of sugar units).

So: Protein = ✔️, Carbohydrate = ❌

2. Has primary, secondary, and tertiary structures

• Proteins: Have primary (amino acid sequence), secondary (α-helix/β-sheet), and tertiary (3D folding) structures.
• Carbohydrates: Do not have these protein - specific structural levels (their structure is based on sugar monomers/polymers).

So: Protein = ✔️, Carbohydrate = ❌

3. May have an alpha helix or a beta sheet

• Proteins: Secondary structures include α - helix and β - sheet.
• Carbohydrates: Do not have α - helix or β - sheet (these are protein - specific secondary structures).

So: Protein = ✔️, Carbohydrate = ❌

Filled Table:

	Protein	Carbohydrate
Has primary, secondary, and tertiary structures	✔️	❌
May have an alpha helix or a beta sheet	✔️	❌

(Note: If the circles are to be filled with "Yes" / "No" or checked/unchecked, use the above logic. For example, mark the Protein column with a check (✔️) and Carbohydrate with an X (❌) for each row.)
