Pectin and cellulose are types of dietary fiber that bind to cholesterol in the intestines, preventing its absorption into the bloodstream. This leads to increased excretion of cholesterol in the feces, which helps lower blood cholesterol levels and reduce the risk of Heart disease.

What is excretion in science?
Excretion is the process by which waste products and harmful substances are removed from the body. It plays a crucial role in maintaining homeostasis by eliminating metabolic waste, excess nutrients, and toxins from the body. Organs such as the kidneys, liver, lungs, and skin are involved in excretion in humans.
Why is cellulose the most abundant molecule on earth?
Cellulose is the most abundant molecule on Earth because it is the main component of plant cell walls, providing structure and support to plants. Plants are widespread and play a crucial role in the ecosystem, leading to the high abundance of cellulose in nature. Additionally, cellulose is produced by photosynthesis, a common process in plants, further contributing to its abundance.
The most important steroid molecule is?
Cholesterol is the most important steroid molecule because it serves as a precursor for the synthesis of other essential steroids in the body, including hormones like cortisol, estrogen, and testosterone. Additionally, cholesterol is a key component of cell membranes and plays a crucial role in maintaining cell structure and function.
Fats are classified as free fatty acids triglycerides phospholipids and?
cholesterol. Each type of fat has different functions and structures in the body, with triglycerides being the most common form of dietary fat stored in adipose tissue for energy. Phospholipids are a key component of cell membranes, while free fatty acids play a role in energy production and various metabolic processes. Cholesterol is essential for cell membrane structure and the production of hormones.
What is the difference between the function of glycogen amylase and cellulose?
All these substances play a major role in the Enzyme activity in plants and animals. Glycogen is the source of energy for the muscles of the body of the human body. Amylase is an enzyme that helps in the making of starch for plant use. Cellulose on the other hand is the primary sugar that allows plants to be able to make their own food
Outermost layer of a plant cell contains pectin?
The outermost layer of a plant cell is the cell wall, which is made up of cellulose, hemicellulose, and pectin. Pectin helps to provide structural support and acts as a barrier to protect the cell from pathogens and environmental stresses. It also plays a role in cell adhesion and communication.
What is the role of the spleen in excretion?
it is helps to filter and clean the blood and removes worn-out red blood cells for excretion.
What organ other than the kidneys play an important role in excretion?
Liver, lungs and skin are other organs of excretion.
What role in cholesterol synthesis and fat metabolism?
the smooth endoplasmic reticulum has the role in cholesterol synthesis, fat metabolism, and detoxification of drugs
Why food is needed?
Fibre or Cellulose is essential because it helps in bowel movement by adding bulk and also it delays gastric emptying which is useful for the diabetic patient. Another major role is it does not allow intestine to absorb dietary cholesterol.
What is the role of cholesterol in angina?
Diet plays a role in heart attacks.
Is the plasma membrane's role excretion?
No, the plasma membrane's main role is to regulate the movement of substances in and out of the cell to maintain cellular homeostasis, rather than excretion. Excretion is the process of removing waste or unnecessary substances from the cell, which is primarily carried out by other cellular structures such as lysosomes or the Golgi apparatus.
What is the role cholesterol in the cell membrane?
Cholesterol allows fluidity in the cell membrane. Cholesterol has a water loving region and also another region which is hydrophobic.
What role do kidneys play in excretion in a frog?
Kidney's filter waste materials from the body.
What substance is a steroid?
Cholesterol: cholesterol plays an important role in the cell membranes of animals and humans. Various hormones are also created from Cholesterol. I got this answer from GradPoint.
What is the role of cholesterol in membranes?
Cholesterol helps the membrane keep its shape and relative size. Cholesterol also helps with cell signaling which is how cells communicate with each other.
What is the role of taurine in lipid digestion?
It plays a role in the oxidation of cholesterol into bile salts in the liver. This allows the cholesterol in to be excreted out of the body by changing it into a water soluble form (bile salts).
