Step by step
Solved in 2 steps
- What are the parts of an amino acid? How does a polypeptide chain form? How is it broken down? Why are there so many different types of protein molecules? Book: Biology (Campbell) 11 edition Urry. Cain. Wasserman. Minorsky. ReeceWhich of the following is NOT TRUE about proteins? Group of answer choices They are composed of amino acids. A change in their structure does not affect their function. They can function as enzymes. They can be found in our diet. They have several levels of protein folding.Which of the following is not a function of a protein? help fight diseases build tissues such as bone and muscle control the rate of reactions and regulate cell processes store and transmit genetic information
- What are proteins? How can the protein diversity of living beings be explained?Which of the following statements about proteins is correct? There are 20 types of amino acids commonly found in proteins. Proteins are composed of glyosidic bonds. Proteins are never folded. They do not contain any hydrophilic or hydrophobic residues. Peptide bonds are composed of only carbon and oxygen atoms.What makes up the backbone structure of proteins? nitrogen and carbon atoms sugars and phosphates the side chains oxygen and nitrogen atoms sulfur and carbon atoms
- There are several different types of carbohydrates and lipids. But there are thousands of different kinds of proteins. Considering the building blocks of proteins compared to the building blocks of carbohydrates and lipids, why do you think there are so many more types of proteins? no handwritten answers please.What are proteins? What type of bonds is responsible for the formation of proteins? Provide an illustration to the second question. What are amino acids? Provide an example of the following by providing their amino acid name and structure: Aromatic amino acid Acidic amino acid Basic amino acid Phenolic amino acid Sulfur containing amino acid Provide the protein/s found in the following: Egg MilkHow many different proteins composed of 100 amino acids could possibly exist?
- What are proteins? What are the four levels of proteins? Explain each level.Which of the following are features of proteins? -they are generally circular molecules. -they are made up of 20 different amino acids. -their synthesis involves the participation of several distinct types of RNA molecule. -unlike DNA, protein never forms a helical structure. -during protein synthesis, the growing chains are extended at the N-terminus More than one answer can be right I am confused please helpwhy would one missing amino acid make a difference in the protein's shape, and why would a change in shape be so important to the functioning of the protein?
