Question

Fan and medal!

Explain carefully what is wrong with the following statements and suggest what should have been said instead

1. The function of the stomach is to digest food

2. The small intestine absorbs your food

3. Amylase breaks down starch into glucose

4. the stomach contains acid because the protease enzyme there works best at ph 2

Answer 1

For the first one say this in your own words. "The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine."

Answer 2

2. small intestine: where most food products are absorbed. helps to break down food, and absorbs nutrients into the bloodstream\

Answer 3

I think three? 3.an enzyme that catalyses the hydrolysis of starch into sugars

Answer 4

@Wolfboy Okay.. so the stomach is not the organ that "digests" the food rather it is the enzymes and acid that does so. The muscles of the stomach simply contract to aid the digestion. Am I correct in saying so?
for the second one I should say, the small intestine is not where all of the food products are absorbed, rather most of them?

Answer 5

I am not the best I biology. But I do believe what you are saying is true. I am doing some research for you in this situation. So yes, I do believe you are correct. i am going to check the small intestine one more time to.

Answer 6

@Wolfboy Thank you very much or your help, I really do appreciate it. I shall write that as the answer.

Answer 7

wait for the small intestine for a second

Answer 8

yes small intestines is correct Its job is to absorb most of the nutrients from what we eat and drink.

Answer 9

@Wolfboy Ahh, okay. Thank you.

Answer 10

This is the best I could find for four. Really sorry.

Gastric acid is a digestive fluid, formed in the stomach. It is composed of hydrochloric acid (HCl) (around 0.5%, or 5000 parts per million) as high as 0.1 M,[1] potassium chloride (KCl) and sodium chloride (NaCl). The acid plays a key role in digestion of proteins, by activating digestive enzymes, and making ingested proteins unravel so that digestive enzymes break down the long chains of amino acids. Gastric acid is produced by cells lining the stomach, which are coupled in feedback systems to increase acid production when needed.

The resulting highly acidic environment in the stomach lumen causes proteins from food to lose their characteristic folded structure (or denature). This exposes the protein's peptide bonds. The gastric chief cells of the stomach secrete enzymes for protein breakdown (inactive pepsinogen and rennin). Hydrochloric acid activates pepsinogen into the enzyme pepsin, which then helps digestion by breaking the bonds linking amino acids, a process known as proteolysis

Parietal cells produce hydrochloric acid, a strong acid that helps to break down food. The acid in your stomach is so concentrated that if you were to place a drop on a piece of wood, it would eat right through it. ­The g-cells produce gastrin, a hormone that facilitates the production of hydrochloric acid by the parietal cells.



This is only information that might help. Sorry but, I didnt want to leave you with nothing. GOOD LUCK :D

Answer 11

@Wolfboy oh wow, that is more than enough, once again thank you ever so much for your help and information you gave me! I really do appreciate it!

Answer 12

NO problem. I an so very glad I could help
