All of the other examples are positive
Answer:
1) By breaking of ATP to ADP
2) The sodium and potassium ions are transported using active transport process!
Explanation:
In cell, the movement of ions across the membrane at the expense of energy is known as Active Transport. The energy is used in the form of ATP(Adenosine Triphosphate) that gets converted to ADP(Adenosine diphosphate) during transport. It takes the ions from high concentration to low concentration. ADP contains one less phosphate group that ATP, as their name indicates and plays a prime role in the flow of energy to the cells.
In the stomach, food undergoes chemical and mechanical digestion. Peristaltic contractions (mechanical digestion) churn the bolus, which mixes with strong digestive juices that the stomach lining cells secrete (chemical digestion). As food travels from your mouth into your digestive system, it's broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion.
