Physics and if not its force
The answer would be a. Energy stored in chemical bonds :)
The reactions of glycolysis are made up of ten steps, out of the ten step three are irreversible, this is because, these reactions have large negative free energies The three steps that are irreversible are:
1. Phosphorylation of glucose.
2. Phosphorylation of glucose 6 phosphate and
3. Transfer of phosphate from phosphoenolpyruvate to ADP.
Answer:
a. Mastication process and formation of bolus in the oral cavity
b. The contraction in the stomach breaks the food down into smaller pieces. These pieces are then moved to the small intestine.
c. In the small intestine, food particles are broken down into nutrients, fat, protein and carbohydrates which are absorbed into the bloodstream.
Explanation:
a. First step of digestive system functioning is the mastication process and formation of bolus in the oral cavity.
b. The contraction in stomach, with the help of digestive enzymes and acids, break the food down into smaller pieces. The small pieces of food are then released into the first part of the small intestine (duodenum).
c. In the small intestine, two enzymes released from pancreas and gall bladder break down the food particles into fats, proteins, and carbohydrates. Thereon, nutrients and carbohydrates, proteins and fats are absorbed into the bloodstream.
