What else can I help you with?
Is the mouth a chemical or mecahnical breakdown?
The mouth is involved in both chemical and mechanical breakdown of food. Mechanical breakdown occurs through chewing and mixing with saliva, while chemical breakdown is initiated by enzymes in saliva that start breaking down carbohydrates.
Is oxidation mechanical or chemical weathering?
Oxidation is a chemical weathering process that occurs when minerals react with oxygen in the air or water, leading to the breakdown of rocks and minerals. This reaction can cause changes in the color and composition of rocks over time.
What part of the digestive system do the mechanical digestion?
Mechanical digestion primarily occurs in the mouth and stomach. In the mouth, teeth break down food into smaller pieces through chewing, while in the stomach, muscular contractions help further break down food into a semi-liquid mixture called chyme.
Although chemical digestion occurs throughout the digestive system it mostly occurs in the?
The stomach and the small intestine are the most important part for digestion. You CAN NOT live without a small intestine, since most nutrients are also absorbed from there also.
Where can secretion and absorption be found in the body?
Secretion and absorption processes primarily occur in the digestive system. Secretion of digestive enzymes and acid takes place in the stomach, pancreas, and small intestine, while absorption of nutrients occurs mainly in the small intestine through its lining known as villi.
Where does water absorption occur in the digestive system?
Water absorption primarily occurs in the small intestine of the digestive system.
What is mechanical degestion and where does it occur?
Mechanical digestion is the physical breakdown of food into smaller pieces through chewing and mixing by the muscular contractions in the digestive tract. It primarily occurs in the mouth through chewing and in the stomach through churning actions.
Where in the body does the process of water absorption into the bloodstream primarily occur?
Water absorption into the bloodstream primarily occurs in the small intestine of the digestive system.
Type of digestion that breaks down food by chemical reactions?
Chemical digestion involves the breakdown of food particles through the action of enzymes. These enzymes help break down complex molecules into simpler forms that can be absorbed by the body. This process occurs primarily in the stomach and small intestine.
Name two regions of the digestive tract where mechanical food breakdown processes are very important?
The mouth (by chewing) and the stomach (by gastric motion).
Saliva pre-digestion through ezymes in saliva is chemical change?
The first chemical change that happens in the body in regards to digestion, the breakdown of foodstuffs, occurs in the stomach. The saliva breakdown would be a physical change.
What part of the Digestive system does chemical digestion takes place?
It occurs from the stomach through the small intestine.
Is the mouth a chemical or mecahnical breakdown?
The mouth is involved in both chemical and mechanical breakdown of food. Mechanical breakdown occurs through chewing and mixing with saliva, while chemical breakdown is initiated by enzymes in saliva that start breaking down carbohydrates.
Where does the oxidation pathway for breakdown of food into ATP occur?
The oxidation pathway for breakdown of food into ATP occurs primarily in the mitochondria of cells. This process involves the breakdown of glucose and other nutrients through a series of reactions that ultimately lead to the production of ATP through the electron transport chain and oxidative phosphorylation.
What climate does WEATHERING by itself occurs fastest in?
Weathering occurs fastest in warm and humid climates, where there is ample moisture to facilitate chemical reactions and physical breakdown of rocks. High temperatures also accelerate chemical weathering processes.
Where in the body does chemical digestion take place and they are controlled by?
Chemical digestion occurs through out the digestive tract with the possible exception of the esophagus. It is regulated by enzymes that help speed it up.
What does the word weathered mean?
Weathering in geology means the chemical and mechanical breakdown of rocks that occurs due to the weakening of these rocks by changes in the environment, such as temperature.
