during digestion, which of the following substances denatures the proteins in food? course hero

Which of the following substances denatures the proteins in food?

Heat, acid, high salt concentrations, alcohol, and mechanical agitation can cause proteins to denature. When a protein denatures, its complicated folded structure unravels, and it becomes just a long strand of amino acids again.

Which of the following foods is naturally a good source of high quality proteins?

Animal-based foods (meat, poultry, fish, eggs, and dairy foods) tend to be good sources of complete protein, while plant-based foods (fruits, vegetables, grains, nuts, and seeds) often lack one or more essential amino acid.

Which of the following amino acids is a dietary essential?

Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—are not synthesized by mammals and are therefore dietarily essential or indispensable nutrients. These are commonly called the essential amino acids.

Does the body need protein to make sodium calcium and other mineral elements?

A. The body needs protein to make sodium, calcium, & other mineral elements. B. The human body normally uses very little protein for energy.

Which of the following substances is an enzyme that participates in the digestion of proteins quizlet?

Which of the following substances is an enzyme that participates in the digestion of proteins? c. Pepsin.

What enzyme is released by the stomach to digest protein?

PepsinPepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin.

Which amino acids are obtained after digestion of proteins?

There are 20 amino acids obtained after digestion of proteins....The different amino acids are as follows:i. Glycinexi. Valine – Valv. Aspartic acidxv. Histidinevi. Glutamic acidxvi. Argininevii. Asparaginexvii. Phenylalanine6 more rows

Which of the following provides amino acids that are best absorbed by the body?

The best sources of amino acids are found in animal proteins such as beef, poultry and eggs. Animal proteins are the most easily absorbed and used by your body. Foods that contain all nine essential amino acids are called complete proteins.

How many amino acids are found in human protein?

Of these 20 amino acids, nine amino acids are essential: Phenylalanine.

What nutrient is important in the transport of oxygen in blood and in muscle tissue and in energy transformation reactions?

Iron has several vital functions in the body. Primarily it is the oxygen carrier of the protein hemoglobin, which is found in red blood cells. Oxygen is essential for cellular metabolism.

Can one kind of protein rich food supply the essential amino acids needed by the body explain?

Although your body can make nonessential amino acids, it cannot make essential amino acids, so you have to get them from your diet. The best sources of essential amino acids are animal proteins such as meat, eggs, and poultry.

When cells have more glucose than they need energy they may convert some of the excess into?

When there is more glucose in the body than required, the resulting excess pyruvate is converted into molecules that eventually result in the synthesis of fatty acids within the body. These fatty acids are stored in adipose cells—the fat cells in the mammalian body whose primary role is to store fat for later use.

Which among the following foods is considered a high quality protein?

Meat – Most animal proteins are considered complete and high-quality. This includes red meat, poultry, and dairy products. Eggs – An average egg is a high-quality protein with approximately 6 or 7 grams of protein. Quinoa – This plant based food includes each of the 9 amino acids that are considered essential.

Which of the following food combinations is an example of complementary proteins?

Combinations of complementary proteins includes: Lentils or legumes with grains, nuts/seeds or dairy. Grain foods with dairy products. Dairy with nuts and/or seeds.

Which of the following is a food that provides ample amounts of all of the essential amino acids?

Meat, poultry, eggs, dairy, and fish are complete sources of protein because they contain all 9 essential amino acids.

What is the DRI for protein quizlet?

The DRI for protein is 0.8 grams of protein per kilogram of body weight per day.
