Unit 7.6: Protein Structure and Function

How are receptor proteins related to our senses?

• Receptor proteins detect and transmit signals from our senses to our brain.

• Receptor proteins are not involved in our senses.

• Receptor proteins are only found in our brain.

• Receptor proteins are responsible for producing our senses.

How does the shape of receptor proteins affect their function?

• The shape of receptor proteins has no effect on their function.

• Receptor proteins with different shapes have the same function.

• The shape of receptor proteins determines their location within the cell.

• The shape of receptor proteins determines their ability to bind to certain stimuli

True or False: The structure of a protein determines its function.

• False

• The structure of a protein has no effect on its function

• True

• The function of a protein determines its structure

True or False: The function of a protein determines the traits of an individual.

• False

• The function of a protein has no impact on traits

• The function of a protein only affects physical traits

• True

What is the primary role of receptor proteins in our body?

• To produce hormones.

• To regulate body temperature.

• To receive and transmit signals

• To store and release energy.

How do changes in the structure of a protein affect its function?

• Changes in the structure of a protein have no effect on its function.

• Changes in the structure of a protein only affect its appearance, not its function.

• Changes in the structure of a protein can improve its function.

• Changes in the structure of a protein can alter its function.

What are some examples of traits that can be influenced by protein function?

• personality traits, susceptibility to diseases, hair texture, metabolism, eye shape

• sense of taste, ability to tan, mucus production, ability to see color

• finger length, taste sensitivity, sleep patterns, body temperature, aging process

• skin color, intelligence, blood type, metabolism, bone density

Explain the relationship between protein structure and function using an analogy.

• Puzzle pieces analogy.

• Lock and key analogy

• Screw and nut analogy.

• Jigsaw puzzle analogy.

How do receptor proteins transmit signals to the brain?

• The signal moves from the receptor protein in the cell to the nerves, to the brain

• Ion channel opening

• Enzyme activation

• Neurotransmitter release
