Answer
Hsp60 is a protein that is typically synthesized in the cytoplasm, where free ribosomes are located. Therefore, this statement is reasonable.
Step 2

Answer
Proteins generally exhibit various levels of structure, including primary, secondary, tertiary, and quaternary structures. Hsp60, like many proteins, does indeed possess a secondary structure, but this statement is quite broad without specific context to Hsp60's structure.
Step 3
C. is produced continuously by a cell.

Answer
While many proteins are produced continuously, the expression of Hsp60 can be context-dependent. It may be upregulated in response to stress but isn't necessarily produced at a constant rate.
Step 4
D. is produced in equal amounts by living cells in a multicellular organism.

Answer
This statement does not accurately reflect the variability in protein expression among different cell types and conditions. Hsp60 may be produced at different levels in various cells according to their requirements.
