Which of the following is an incorrect statement with regard to the Digestive activities

Options

A. glucose and amino acid are the end products of starch and protein digestion respectively
B. fatty acids and glycerol are absorbed in the form of micelles in enterocytes. These these micelles are then transported to lacteals as such
C. Absorption of water some mineral and drugs takes place in large intestine
D. Defaection is a voluntary process which is carried out by a mass peristaltic movement

Answer

To determine which statement regarding digestive activities is incorrect, we will analyze each statement provided in the question step by step.

### Step 1: Analyze the First Statement
**Statement:** "Glucose and amino acid are the end product of starch and protein digestion respectively."

- **Explanation:** Starch is a polysaccharide made up of glucose units. The digestion of starch begins in the mouth with salivary amylase, which breaks down starch into maltose and dextrins. In the small intestine, pancreatic amylase further digests these products into glucose. Proteins, on the other hand, are made up of amino acids. They are digested by enzymes like pepsin in the stomach and trypsin in the small intestine, ultimately resulting in amino acids.
- **Conclusion:** This statement is true.

### Step 2: Analyze the Second Statement
**Statement:** "Fatty acid and glycerol are absorbed in the form of micelles in the enterocytes and these micelles are transported to the lacteals as such."

- **Explanation:** Fatty acids and glycerol are indeed absorbed in the form of micelles, which are formed in the intestinal lumen. However, once they enter the enterocytes (intestinal cells), they are reassembled into triglycerides and then packaged into chylomicrons. These chylomicrons are then transported into the lymphatic system via lacteals. Therefore, micelles do not directly enter the lacteals.
- **Conclusion:** This statement is false.

### Step 3: Analyze the Third Statement
**Statement:** "Absorption of water, some minerals, and drugs take place in the large intestine."

- **Explanation:** The large intestine primarily functions to absorb water and electrolytes, as well as some minerals and certain drugs. It does not engage in significant digestive activity but plays a crucial role in the absorption process.
- **Conclusion:** This statement is true.

### Step 4: Analyze the Fourth Statement
**Statement:** "Defecation is a voluntary process which is carried out by the mass peristaltic movement."

- **Explanation:** Defecation is indeed a voluntary process that involves the coordinated contraction of the muscles in the rectum and anus. Mass peristaltic movements help push the feces towards the rectum, and the process is initiated by the filling of the rectum, leading to the urge to defecate.
- **Conclusion:** This statement is true.

### Final Conclusion
After analyzing all the statements, the incorrect statement regarding digestive activities is the second statement: "Fatty acid and glycerol are absorbed in the form of micelles in the enterocytes and these micelles are transported to the lacteals as such."
