Which of the following is NOT a function of proteins?(1 point)
Responses
control the rate of reactions and regulate cell processes
control the rate of reactions and regulate cell processes
used to form bones and muscles
used to form bones and muscles
store and transmit heredity
store and transmit heredity
help to fight disease
store and transmit heredity
The correct answer is: store and transmit heredity.
To determine which of the options is NOT a function of proteins, let's analyze each option:
1. Control the rate of reactions and regulate cell processes: Proteins known as enzymes play a crucial role in catalyzing chemical reactions and regulating cellular processes. Therefore, this option is a function of proteins.
2. Used to form bones and muscles: Proteins such as collagen make up a significant portion of bones, while muscle fibers are composed primarily of proteins called actin and myosin. Thus, this option is also a function of proteins.
3. Store and transmit heredity: This statement is incorrect. Proteins do not store or transmit hereditary information; instead, this role is fulfilled by nucleic acids, particularly DNA and RNA.
4. Help to fight disease: Antibodies, a type of protein, are essential components of the immune system and are involved in combating diseases. Therefore, this option is also a function of proteins.
Based on our analysis, the option that is NOT a function of proteins is: store and transmit heredity.
