tricuspid valve
mitral valve
The mitral valve prevents a backflow of blood into the left atrium. It closes when the heart contracts, preventing blood from flowing back. Other valves like the aortic and tricuspid have different functions.
The mitral valve, also known as the bicuspid valve, is the valve that prevents a backflow of blood into the left atrium. This valve is located between the left atrium and the left ventricle. When the heart contracts, the mitral valve closes, preventing blood from flowing back into the atrium. The other valves listed, the aortic valve and the tricuspid valve, have different functions. The aortic valve controls blood flow from the left ventricle into the aorta, and the tricuspid valve prevents backflow of blood into the right atrium.

Without enzymes, the body couldn't perform essential chemical reactions quickly enough to sustain life. Enzymes also aid digestion and help in immune defence. Their absence would critically interrupt bodily functions and overall health.
If there were no enzymes in the human body, many essential biological processes would be negatively impacted. Enzymes act as biological catalysts, speeding up the chemical reactions that occur within cells, thereby allowing life-sustaining processes to occur at the rate necessary for life. If we didn't have enzymes, these reactions would happen too slowly to sustain life, or might not happen at all.
Enzymes are vital in breaking down food and converting it into usable energy. Without enzymes, our digestive system would not be able to efficiently break down nutrients, leading to malnutrition and energy deficiency. Moreover, enzymes are involved in the immune system's defence mechanisms. They assist in the destruction of foreign pathogens, thus protecting the body from infections.
Furthermore, each cell's enzyme demand changes according to its needs and role within the body. For instance, the enzymes necessary in stomach cells differ from those in skin, blood, or nerve cells reflecting the diverse functions enzymes perform in the human body.
Overall, without enzymes, the human body would be unable to function properly. They are essential for our survival, and their absence would dramatically alter the way our bodily systems operate.

Answer: Amino acids; peptide
Explanation:
20 different AMINO ACIDS link together to form chains. A protein is composed of one or more of these PEPTIDE chains which are twisted and folded into a particular shape.
There exists 20 amino acids capable of forming protein in the Human body. At least two amino acids are joined together by a peptide bond to form polypeptide chains that are then held together by hydrogen bonds in twisted alpha helical structures to form proteins.
Answer:Amino acid, polypeptide/polynucleotide chains
Explanation: Amino acids are usually the building blocks of protein hence,every protein is made up of one or more amino acids.
A protein consist of one or more polypeptide chain that is folded into a helix shape. This shape is to prevent the easy degradation of the components that makes up the polypeptide because it is water loving and can easy degrade.
