Sucrose is a disaccharide, composed of the monosaccharides glucose and fructose. The hydrolysis of sucrose by the enzyme sucrase results in
A)bringing glucose and fructose together to form sucrose.
B)the release of water from sucrose as the bond between glucose and fructose is broken.
C)breaking the bond between glucose and fructose and forming new bonds from the atoms of water.
D)production of water from the sugar as bonds are broken between the glucose monomers.
E)utilization of water as a covalent bond is formed between glucose and fructose to form sucrase.

Question

Quizplus · Accepted Answer

The hydrolysis of sucrose by the enzyme sucrase involves breaking the covalent bond between glucose and fructose, and forming new bonds between the atoms of water. This process is called dehydration synthesis, and it results in the formation of glucose and fructose as separate monosaccharides. Option A is incorrect because sucrase does not bring glucose and fructose together to form sucrose; rather, sucrose is the substrate for sucrase. Option B is incorrect because hydrolysis involves the addition of water to break a covalent bond, not the release of water. Option D is incorrect because water is not produced from the sugar during hydrolysis. Option E is incorrect because water is not used as a covalent bond to form sucrase, which is a protein and not a sugar.
