Biology
1 answer:
AURORKA [14]3 years ago
5 0

Answer:

Mouth: The process of food breakdown first begins in the mouth. The tooth, tongue and jaw apply this process with a mechanical activity. While teeth provide mechanical digestion of food, saliva chemically digests food.

YUtta and esophagus): The tongue pushes the food towards the esophagus. Meanwhile, the trachea is covered with a laryngeal lid. When swallowed food reaches the esophagus, the esophagus contracts peristaltic movements, allowing the food to move towards the stomach.

Stomach: The stomach is an organ that stores food, breaks it down mechanically and secretes enzymes to digest proteins. The secretion of gastric juice is provided by the gastrin hormone. The stomach is an acidic environment. This acid kills bacteria in food and converts proteins into amino acids in enzymes in the stomach. Ultimately, a mixture of partially digested nutrients called chyme is obtained. This mixture is sprayed into the small intestine. Vitamin B12 is a vitamin that is released from the stomach.

Igestion of carbohydrates within the small intestine involves enzymes that come from the? a: mouth. b: stomach. c: pancreas. d:
ella [17]

Enzymes come from the pancreas.

What are Enzymes?

Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.

The small intestine, not the stomach, is where carbohydrates are chemically broken down. The chemical breakdown of digestible carbohydrates is completed by disaccharidases and pancreatic amylase. The circulation carries the monosaccharides to the liver after absorption.
