Do plants undergo digestion?
sure why not
Does water undergo chemical digestion in the stomach?
Water remains water throughout the digestion process. It is not broken down into oxygen and hydrogen.
Which organic compound undergo partial chemical digestion in the human mouth?
carbohydrates
What nutrient do not undergo any chemical digetion in the stomach?
Fats do not undergo any significant chemical digestion in the stomach. While enzymes like gastric lipase are present, the primary digestion of fats occurs in the small intestine with the help of bile and pancreatic enzymes. The stomach mainly serves to mechanically break down food and mix it with gastric juices, while chemical digestion of carbohydrates and proteins begins there.
A Ligand that cannot cross the cell membrane can send message to a cell by binding to a?
A ligand that cannot cross the cell membrane can send a message to a cell by binding to a cell surface receptor. These receptors, typically located on the extracellular portion of the cell membrane, undergo a conformational change upon ligand binding, triggering a cascade of intracellular signaling pathways. This process allows the cell to respond to external signals despite the ligand's inability to penetrate the membrane. Examples of such ligands include peptide hormones and neurotransmitters.
How Monosaccharides have to be broken down many times during digestion true or false?
False. Monosaccharides, such as glucose and fructose, are the simplest form of carbohydrates and do not need to be broken down further during digestion. They are absorbed directly into the bloodstream from the small intestine after the digestion of more complex carbohydrates. Therefore, they do not undergo multiple breakdown processes like polysaccharides or disaccharides.
Are mollusks asexual?
Most mollusks reproduce sexually, but many of them are also hermaphroditic (both male and female), and are able to impregnate others while also becoming pregnant themselves. Some mollusks, like clams, simply broadcast huge quantities of sperm into the environment, and hope that eventually it finds another clam. Some, like many squid, have two sexes and a series of elaborate courtship rituals they undergo before mating takes place.
What biomolecule is chemically digested in the stomach?
In the stomach, proteins are the primary biomolecules that undergo chemical digestion. The acidic environment, primarily due to hydrochloric acid, activates pepsinogen into pepsin, an enzyme that breaks down proteins into smaller peptides. While some lipid digestion begins in the stomach, it is mainly the proteins that are significantly processed during this stage of digestion. Carbohydrates are largely unaffected until they reach the small intestine.
Does a butterfly have a coiled shell?
No, a butterfly does not have a coiled shell. Butterflies are insects with a soft body and an exoskeleton, but they do not possess a shell like mollusks such as snails or clams. Instead, butterflies have wings covered in scales and undergo metamorphosis, transitioning from larva to pupa before becoming an adult.
What is underwent (to) undergo?
of Undergo, imp. of Undergo.
How are the life cycles of a mollusks and insect different?
Mollusks typically have a simpler life cycle that includes stages such as eggs, larvae (like trochophore or veliger), and adult forms, often undergoing direct development or limited metamorphosis. Insects, on the other hand, usually experience complete metamorphosis, which consists of distinct stages: egg, larva, pupa, and adult, or incomplete metamorphosis, which includes egg, nymph, and adult stages. Additionally, many insects undergo significant changes in morphology and behavior during their metamorphic stages, while mollusks generally exhibit more gradual changes as they mature.
What packages up protein for release from the cell?
Proteins are packaged for release from the cell in the Golgi apparatus. Here, they undergo modifications and are sorted into vesicles that transport them to their designated locations, either within the cell or for secretion outside the cell. These vesicles then fuse with the cell membrane, releasing the proteins into the extracellular space.
