Digestive System

Both DNA and RNA, present in the nuclei of cells forming the ingested foods, are hydrolyzed to their nucleotide monomers by pancreatic nucleases present in pancreatic juice. The nucleotides are then broken apart by intestinal brush border enzymes, which release their free bases, pentose sugars, and phosphate ions.

No, peroxisomes do not function to digest particles ingested by endocytosis. They are responsible for breaking down long-chain fatty acids, amino acids, and toxins in the cell. Endocytosis is a process where cells engulf particles into vesicles for digestion in lysosomes.

The chewed up lump of food is known as a bolus.

No, amylase is not active at such a low temperature and would not be able to break down the starch into simpler sugars. Therefore, you would not expect to see any significant digestion of starch at zero degrees Celsius.

The organisms play a vital role in decomposition, breaking down complex organic matter into simpler nutrients that can be recycled and used by other organisms in the ecosystem. This process helps to cycle essential nutrients like carbon, nitrogen, and phosphorus, contributing to the overall health and balance of the ecosystem.

1. Amylase breaks down starches into sugars.
2. Proteases break down proteins into amino acids.
3. Lipases break down fats into fatty acids and glycerol.
4. Cellulase breaks down cellulose into glucose.
5. DNA polymerase helps in DNA replication by synthesizing new DNA strands.

The green liquid that breaks down large droplets of fat into small droplets of fat is called bile. Bile is produced by the liver and stored in the gallbladder before being released into the small intestine to aid in the digestion and absorption of fats.

Well... BASICALLY... they aren't even in washing powder, washing powder consists of tiny women, with really small sponges, who clean, and then cover your clothes in not very nice smelling odurs. I hope this helped. Love 11YD1 Science.

The primary organs associated with digestion are the mouth, stomach, small intestine, and large intestine. These organs work together to break down food, absorb nutrients, and eliminate waste from the body.

Microorganisms in rabbits and horses primarily digest fiber in the cecum and colon. These organs contain a diverse population of bacteria, fungi, and protozoa that ferment fiber-rich plant material, breaking it down into nutrients that can be absorbed by the host animal. This process is essential for extracting energy from the cellulose and hemicellulose found in the diets of these herbivores.

Large food molecules are first broken down into smaller molecules through hydrolysis reactions. Enzymes facilitate this process by catalyzing the breakdown of bonds within the large molecules. The resulting smaller molecules can then be absorbed and utilized by the body for energy or building processes.

Consuming dietary fats helps the body absorb fat-soluble vitamins A, D, E, and K. These vitamins require fat to be absorbed in the intestines and then transported throughout the body. Including sources of healthy fats like nuts, seeds, avocados, and oils can enhance the absorption of these vitamins.

Amylase is an enzyme that breaks down starches into smaller molecules like maltose and glucose by catalyzing the hydrolysis of glycosidic bonds. It primarily functions in the mouth and small intestine to initiate the digestion of complex carbohydrates into simpler sugars that can be absorbed by the body for energy.

The end product of pepsin digestion is peptides, which are smaller fragments of proteins. Pepsin breaks down proteins into peptides by hydrolyzing peptide bonds between amino acids. These peptides can be further broken down into individual amino acids by other digestive enzymes for absorption in the small intestine.

Cohesins break down during the metaphase-anaphase transition of mitosis or meiosis. This breakdown allows sister chromatids to separate and move towards opposite poles of the cell.

The target molecule for an enzyme is called the substrate. Enzymes bind to specific substrates and catalyze chemical reactions to convert the substrate into a product.

the enzyme produced in the stomach wall is mainly protease, this breaksdown the proteins in the food you have eaten

Yes, digestion is an adaptation that allows organisms to break down food into smaller molecules that can be absorbed and used for energy and nutrients. This process involves different organs and enzymes working together to extract nutrients from food.

Absorption.

The medical term for this procedure is "percutaneous transhepatic cholangiography" (PTC). It involves using a needle to pass through the liver to inject contrast medium into the bile ducts to visualize their structure.

The lining of the small intestine is covered with tiny projections with many capillaries. The projections are called villi. Nutrients pass into the capillaries of the villi and then to other organs of the body.

Pancreatic acinar cells produce the enzyme lipase. Lipase is secreted by the pancreas into the small intestine, where it helps to break down fats into fatty acids and glycerol for absorption into the bloodstream.

Smaller and simpler molecules that can be absorbed by the body, such as glucose, amino acids, and fatty acids.

The major enzyme associated with saliva is amylase, which helps break down carbohydrates into sugars during digestion. Amylase plays a crucial role in the initial stages of breaking down food in the mouth before it travels to the stomach and intestines for further digestion and absorption.

The product of digestion present in baby food is usually a combination of broken down macronutrients such as carbohydrates, proteins, and fats. These smaller molecules are easier for babies to digest and absorb for growth and development.
