Mark all true statements about turns and loops:
a They are generally located in the interior of proteins.
b They can interact with other proteins and the environment.
c Loops are found only on β sheets.
d Loops exposed to an aqueous environment are usually composed of hydrophilic amino acids.
Homework Answers
Turns and loops;
b. interact with other protein and the enviornment. d. Loops exposed to an aqueous environment are usually composed of hydrophilic amino acids.
Explanation:1. They generally lie on the surface of the protein. So, they participate in interactions between proteins and other molecules
2. In loops, the CO group of residue of a polypeptide is hydrogen bonded to the NH group of residue . This interaction stabilizes abrupt changes in direction of the polypeptide chain
a They are generally located in the interior of proteins.----> FALSE (They are exposed to outside environmnet)
b They can interact with other proteins and the environment. ----->TRUE (As they are present on exterior of proteins, they are able to interact with other proteins).
c Loops are found only on β sheets.------> (alpha sheets or alphs helices also contains turns and loops).
d Loops exposed to an aqueous environment are usually composed of hydrophilic amino acids. ----> TRUE

6) Proteins are composed of amino acids polymerized into long chains. The structure of a protein - that is, its overall shape and how the chains are "folded” around each other - is very important for its function. In an aqueous environment, in an active, folded state the hydrophilic amino acids in the protein are facing outwards exposed to the water and the hydrophobic amino acids are hidden away from the water in the core of the protein. In a...

Select all of the following statements that are true about potential energy and conservative forces. Potential energy is the energy associated with the configuration of a system. It is only possible to have potential energy if there are 2 or more objects in the system that interact with each other through internal, conservative forces. Absolute values of potential energy have no meaning: only changes in the potential energy are physically meaningful. There is only one kind of potential energy: gravitational...
