Answer:
Digestion
Explanation:
The diagram is attached below
The diagram represents a complex sugar that is linked to an enzyme. With the addition of water, this complex sugar is broken down into two simple sugars.
This process is called digestion, which is the breakdown of large insoluble molecules into small molecules that the body can use for energy. The catalyst in this picture speeds up or facilitates the reaction. It could be an enzyme such as amylase.
Answer:
The correct answer is option D) "a quaternary protein with four polypeptides".
Explanation:
Hemoglobin is a quaternary protein with four polypeptides. Hemoglobin is comprised of four polypeptides, two alpha chains with 141 amino acid residues and two beta chains with 146 amino acids residues. Hemoglobin is classified as a quaternary protein, because it reaches a quaternary structure when the different polypeptides are attached to each other.
