Answer:
Enzymes speedup the chemical reaction.
Explanation:
Enzymes are the molecules which are responsible for speedup of the chemical reaction. In this picture, we can see substrate attached to the active site of the enzyme. This enzyme speedup the chemical reaction and products are formed after completion of chemical reaction. When the chemical reaction is over, the products detached from the enzyme and no decrease occurs in the size of enzyme.
Fibre is a carbohydrate that the body can not digest or assimilate
There are two types of fibre: soluble fibre and insoluble fibre with complementary health benefits.
<span>Fibre that soluble can bind to bile and cholesterol and pull it out of circulation. this can help to decrease blood cholesterol.</span>
Food molecules contain chemical energy which is released when its chemical bonds are broken.
Food undergoes digestion in the digestive system and is broken down into its monomer units. Carbohydrates, which are the principal source of energy, are broken down into glucose. Glucose is the monomer unit of carbohydrates.
Glucose then is taken up by cells and is used in cellular respiration, which involves three main stages namely glycolysis, Krebs cycle and the electron transport chain, through which a glucose molecule is processed to form at least 36 molecules of ATP.
ATP is the form of energy that cells use.
The answer to this question is option D
