Chapter 3 Non-enzymatic Function

Question 1

Common structural proteins in a cell

Answer 1

Actin, collagen, keratin, Tubulin, Elastin

Question 2

Commonality to structural proteins, in terms of their structure

Answer 2

Many have a repeating secondary structure, allowing these to interact with each other.

Question 3

Two polar structural proteins

Answer 3

Actin & Tubulin

Question 4

Motor protein (definition)

Answer 4

Proteins that exhibit some capability to transform across the cell, displaying enzymatic activity

Question 5

Kinesins and dyneins interact with what cytoskeletal feature?

Answer 5

Microtubules

Question 6

Kinesins and dyneins travel in different directions and are responsible for vesicle transport. Which protein goes in which direction?

Answer 6

Kinesins go in the positive direction while Dyneins go in the Negative direction, toward the negative pole of the microtubule.

Question 7

Binding proteins, definition

Answer 7

Binding proteins stabilize some sort of molecule but don’t have structural or enzymatic function
