If denaturation occurs (extreme temperature change or pH changes), the enzyme will not be reusable! The structure of the enzymes are not changed. As a result of this, enzymes will be used again and again to bind onto another substrate molecule and catalyze the reaction once again.
C. The cell must be a plant cell.
Only plant cells have cell walls. Bacteria cells and animal cells do not. Both animal cells and plant cells have membrane-bound organelles, but since the student saw a cell wall, it must be a plant cell.
Hope this helps! :)

Answer:b. Amino acid sequence, hydrogen bonding between backbone groups, the overall shape of a single polypeptide, and combinations of tertiary structures.
Explanation: Primary structure is the amino acid sequence in the polypeptide chain. When the sequence is altered due to mutation it can lead to formation of entirely new amino acid sequence.
Secondary structure could be the helical structure or the Beta pleated sheet. It is form from the interaction of atom that are backbones.It is the hydrogen bond between amino Hydrogen and carboxyl oxygen atom in the backbones
Tertiary structure- Overall structure of polypeptide. It result from interaction of the R groups amino acids. It gives the shape of the polypeptide.
Quantenary- Are protein made up of multiple polypeptide chain. This chain are also called subunit. It is the combination of all tertiary structures given rise to a functional protein.
