Question

There are two rules when it comes to muscles and proteins:

Proteins like to change ______________________ when stuff binds to them.
Changing shapes can allow proteins to _________________________________ with other stuff.
a. Color; Interact
b. Shape; Bind
c. Texture; Repel
d. Size; Expand

Answer 1

Proteins change their shape when substances bind to them, which allows them to interact with other molecules or structures. This fundamental property is critical for muscle function and various other biological processes.

Step-by-step explanation:

Regarding the two rules about muscles and proteins:

1. Proteins like to change shape when stuff binds to them.
2. Changing shapes can allow proteins to bind with other stuff.

These principles are fundamental in understanding how proteins function in biological systems. The shape of proteins is critical to their function, with many different types of chemical bonds maintaining this shape. Fibrous proteins, such as those in muscle tissue, enable muscles to contract and relax due to their long, slender shape, while globular proteins like hemoglobin are responsible for other functions like transport of oxygen. Changing the shape of proteins, a process influenced by factors such as temperature and pH, can lead to denaturation and loss of function.
