Explain why chemical digestion does not begin in the mouth for all foods?
Chemical digestion in the mouth primarily involves the breakdown of carbohydrates by the enzyme amylase in saliva. Not all foods require significant carbohydrate digestion, such as proteins and fats. Therefore, chemical digestion for these macronutrients begins further down the digestive tract, where specific enzymes like pepsin and lipase are present.
What begins in the chemical digestion of foods containing?
In the chemical digestion of foods containing carbohydrates, enzymes in the saliva, such as amylase, start breaking down starches into simpler sugars like maltose. This process continues in the small intestine with enzymes like pancreatic amylase that further break down complex carbohydrates into glucose for absorption.
What carbohydrates require a process of digestion in order to be broken down into glucose and help maintain proper blood sugar levels?
Complex carbohydrates such as starches found in foods like whole grains, vegetables, and legumes require digestion to break down into glucose and help maintain proper blood sugar levels. These carbohydrates provide sustained energy and are digested more slowly than simple carbohydrates.
Which procedure would have the least effect on the rate of protein digestion?
Consuming protein with carbohydrates or fats slows down the rate of protein digestion because they require different enzymes to break down in the stomach. Eating protein-rich foods alone, without carbohydrates or fats, would have the least effect on the rate of protein digestion.
Why is it helpful to know the the physical and chemical properties of a substance?
In is impossible to work with materials, substances etc. without a deep knowledge of all chemical and physical properties. And all around us: foods, building materials, electronics, cars, drugs are composed from materials with specific properties.

What type of digestion is used to break down small foods particles by enzyme action?
"chemical" or "chemical digestion"
Describe the chemical reaction that takes place in tahe decay of foods growth of plantd digestion of food?
what is chemical reaction taking place in the delay of foods growth of pro digestion of foods
What does chemical digestion in the stomach require?
The process of chemical digestion starts is your mouth! When you start chewing, your saliva helps break down the food as it goes down the esophagus.
What process increases the surface area of foods prior to chemical digestion?
Mechanical digestion is the process that increases the surface area of foods prior to chemical digestion. This process involves chewing, churning in the stomach, and segmentation in the small intestine to physically break down food into smaller pieces, allowing enzymes to work more efficiently.
Which process increases the surface area of foods prior to chemical digestion?
chewing
Which of the following processes involves both physical and chemical changes?
Rusting of iron involves both physical and chemical changes. The physical change involves the formation of iron oxide on the surface of iron, while the chemical change involves the reaction of iron with oxygen in the presence of water to form iron oxide.
What are the two kinds of digestion and how are they different?
Long time ago when I studied this but I think you are looking at physical and chemical. Physical digestion is masticulation, chewing, crushing, grinding etc and takes place in the mouth. Chemical digestion is the breakdown of foods by substances such as bile acids etc. This process also starts in the mouth as saliva contains some digestive acids, but in the main part takes place in the large intestine.
What are chewing and churning types of?
Chewing and churning are types of mechanical digestion. The other type of digestion is chemical digestion, which involves the breaking down of foods via enzymes.
What is the similarities between mechanical and chemical digestion?
They both break down food. Mechanical digestion literally breaks it down by grinding it. Whereas chemical digestion uses amylase (saliva that contains an enzyme) To break down the foods from starch to simple sugars.
What organs secrete enzymes which begin chemical digestion in the mouth?
The salivary glands in the mouth secrete enzymes in saliva that begin chemical digestion.
Is food decays a physical change?
Foods degradation is a chemical process.
