Question

Explain the importance of ph in to decay and in our digestive system

Answer 1

Answer:

Explanation:

Tooth decay:-

bacteria present in the mouth produces acids by degradation of sugar and food particles remaining in the mouth after eating (if pH is below 5.5)

Using toothpaste which are generally basic for cleaning the teeth can neutralize the excess acid and prevent tooth decay.

PH in our digestive system:-

as the match produces hydrochloric acid which helps in digestion of food without harming the stomach in digestion the stomach produce too much of acid which cause pain and irritation .

We use antiacids which neutralize the excess acid.

Ex-magnesium hydroxide

Answer 2

All living organisms need nutrients to survive. While plants can obtain nutrients from their roots and the energy molecules required for cellular function through the process of photosynthesis, animals obtain their nutrients by the consumption of other organisms. At the cellular level, the biological molecules necessary for animal function are amino acids, lipid molecules, nucleotides, and simple sugars. However, the food consumed consists of protein, fat, and complex carbohydrates. Animals must convert these macromolecules into the simple molecules required for maintaining cellular function. The conversion of the food consumed to the nutrients required is a multistep process involving digestion and absorption. During digestion, food particles are broken down to smaller components, which are later absorbed by the body. This happens by both physical means, such as chewing, and by chemical means.
