What else can I help you with?
Why does most of the food you eat need to be digested?
All food contains complex substances such as carbohydrates, proteins and fats. The body cannot utilise these substances in their complex form. The food consumed is broken down into simpler substances by a procedss called digestion. The digested food can be easily absorbed by the body.
Carbohydrates that cannot be digested by the body are called?
Fiber.
What do enzymes help digestion?
Enzymes are involved in the digestion of all types of foods except, of course, the foods that cannot be digested (like cellulose).
What is subtance that cannot be digested?
The substance that cannot be digested is known as dietary fiber. It consists of plant-based carbohydrates that the human digestive system cannot break down. Fiber aids in digestion by promoting regular bowel movements and can help prevent constipation, but it passes through the digestive tract largely intact. There are two types of fiber: soluble and insoluble, both of which play important roles in maintaining health.
What is a simple complex carbohydrate?
There is no such thing as a simple complex carbohydrate. Carbohydrates are either simple or complex; they cannot be both.
Is your body able to absorb food if it is not chemically digested?
No, the body cannot absorb food that has not undergone the process of chemical digestion. Digestion breaks down food into nutrients that can be absorbed by the body through the walls of the intestines. If food is not chemically digested, the nutrients remain in a form that the body cannot utilize.
Why is digestion and absorption of lipids more complex than carbohydrates?
Digestion and absorption of lipids is more complex than carbohydrates because lipids are hydrophobic, meaning they repel water. This requires additional steps for lipid digestion, such as emulsification to break down large fat globules into smaller droplets. Additionally, lipids are absorbed into the bloodstream through specialized structures called micelles and chylomicrons, whereas carbohydrates are usually absorbed as simple sugars directly into the bloodstream.
Which carbohydrate cannot be digested by humans and how does it help in digestive system?
cellulose. humans do not possess the enzymes necessary for its digestion.
Can starch diffuse into the human blood stream without being digested?
No, starch cannot diffuse into the human bloodstream without being digested. Starch is a complex carbohydrate that must first be broken down into simpler sugars, primarily glucose, through the process of digestion. This breakdown occurs in the mouth and small intestine via enzymes like amylase. Only after starch is digested into glucose can it be absorbed into the bloodstream.
Which of the following cannot be digested by humans-sucrose maltose cellulose or fructose?
Cellulose cannot be digested by humans.Cellulosecellulosehumans cannot digest cellulosecelluloseCelluloseCellulose (aka Fiber) can not be digested by humans because, we don't have the bacteria needed to break down cellulose. Sucrose, Maltose, and Fructose are all disaccharides (carbohydrates/sugars) and are all able to be broken down to glucose in the body.
Which process is most aided by the presence of bacteria in the human body?
Digestion is the process most aided by the presence of bacteria in the human body, as they help break down complex carbohydrates in the gut that our own enzymes cannot digest.
What is digestion of food is it is reversible or it irreversible?
Digestion of food is the biochemical process by which the body breaks down food into smaller, absorbable components, such as nutrients and energy. This process involves mechanical and chemical actions, including the secretion of enzymes and acids. Digestion is generally considered irreversible, as it transforms complex food substances into simpler molecules that cannot be reassembled into their original form within the body. Once food is digested and absorbed, it cannot be reverted back to its initial state.
