Enzymatic breakdown of which of the following compounds doesn’t begin until it reaches the stomach?

Biology
1 answer:
ahrayia [7]3 years ago
5 0

Answer:

B. Proteins

Explanation:

Salivary amylase is an enzyme that starts the breakdown of starch in the mouth. Gastric glands of the stomach secrete gastric juice, which contains HCl to kill bacteria and denatures proteins, intrinsic factors, and the enzyme pepsin. The chief cells of gastric glands secrete pepsinogen (an inactive form of pepsin).

Pepsin begins the digestion of proteins in the stomach. It breaks down certain peptide bonds between amino acids and thereby, breaks down protein chain into smaller peptide fragments. Pepsin requires a very acidic environment of the stomach (pH 2) and becomes inactive at a higher pH.

What does it mean for a membrane to be selectively permeable?
maw [93]

Answer;

Semi-permeability means that only certain molecules are allowed to pass through.

Explanation;

-Semi-permeability is one of the features of a cell membrane, which means that the membrane allows selective movement of materials in and out of the cell; that is only certain molecules can enter or leave the cell.

-For example smaller molecules such water and ions such as potassium and sodium ions are able to leave and enter the cell, while other molecules that are large such as protein molecules can not enter or leave the cell.

What is the relationship between the rate of wind and the amount of abrasion?
Andreyy89

Answer: Wind speed is also important. The rate of erosion caused by a 30-mile-per-hour wind is more than three times that of a 20-mile-per-hour wind. Wind erosion decreases as soil moisture increases. For example, dry soil erodes about one-and-one-third times more than soil with barely enough moisture to keep plants alive.

Describe the source of food for the first 3 levels in the food chain and explain why it takes less land, water, air to produce a
Ronch [10]
This question is incomplete as the specific food chain is not provided. In general, a food chain will have a primary producer at the base of the chain. This is an organism that is able to utilise a form of energy to convert carbon dioxide in the atmosphere to a carbohydrate. For terrestrial food chains, these are typically plants, who by utilising the energy from the sun, are able to convert carbon dioxide to carbohydrates. The subsequent level in the food chain may be a primary consumer, typically herbivores, that consume plant matter. Subsequent links in the chain would typically be secondary consumers, who would be carnivores, omnivores or decomposers. Carnivores would typically be predators and would be at the apex of the food chain. Energy is lost from one link to the subsequent link in the food chain, through basic respiration and inefficient energy transfer from one link to another. This explains why more resources (land, water and air) are required to grow meat rather than plant matter. More of the sun's energy is available within the lower trophic levels in a food chain, before much of it is lost as energy moves up the food chain. An easy example to illustrate this is that much of the livestock raised in the USA is fed grain. If people rather ate the grain than the livestock, they could obtain all their required energy from a smaller amount of grain then would be needed to raise the meat they require.
