Attempt History Attempt Time Score KEPT Attempt 2 6 minutes 16 out of 16 LATEST Attempt 2 6 minutes 16 out of 16 Attempt 1 19 minutes 15.7 out of 16 Score for this attempt: 16 out of 16 Submitted Nov 18, 2022 at 11:33p.m. This attempt took 6 minutes. Pre-Reading Quizzes are intended to give you an excuse to look over the Pre-Reading Material before you get to class. They are not designed for you to all of your learning here. This of them as a 'first exposure' so that you know before class what some of the hard parts are. Each quiz is worth 0.5%, and we will count the best 6 of 9 quizzes. Use the Pre-Reading Guide (https://canvas.ubc.ca/courses/113307/files/21929916/download?wrap=1) (https://canvas.ubc.ca/courses/113307/files/21929916/download?download_frd=1) to help you remain active as you read the online notes, and don't forget to do the Pre-Reading Feedback Survey (https://canvas.ubc.ca/courses/113307/quizzes/531579) afterwards , so that we know what parts of this week's readings were the most challenging! 2 / 2 pts Question 1 Which of the following statements about the cytoskeleton is true? Choose all that apply.

Correct! Correct! Microtubules are the smallest filament. The cytoskeleton of a cell can change in response to the environment. Correct! Correct! Actin is the smallest filament. Correct! Correct! Covalent bonds between the protein monomers hold together cytoskeletal filaments. Intermediate filaments are so named because their size is 'intermediate', compared to the other two. Correct! Correct! The cytoskeleton controls the location of organelles in eukaryotic cells. Correct! Correct! Great work! 1 / 1 pts Question 2 The black lines in the three images below each represent one of the types of skeletal filament. The nucleus is shown as a grey circular structure near the centre of these animal cells.

Image A (lines originate from single central source) Microtubules Correct! Correct! Image B (lines everywhere, including around the nucleus) Intermediate Filament Correct! Correct! Image C (very thin lines, primarily right under the surface of the PM) Actin Filaments Correct! Correct! Great work! 3 / 3 pts Question 3 For each of the statements below, match it to the cytoskeletal filament that it applies to. Monomer that binds ATP actin filaments Correct! Correct! Includes keratin and neurofilaments intermediate filaments Correct! Correct! Used in the eukaryotic flagellum microtubules Correct! Correct! Can be connected through desmosomes intermediate filaments Correct! Correct!

Correct! Their stability involves a GTP cap microtubules Correct! Correct! A component of the mitotic spindle microtubules Correct! Correct! Important for formation of the contractile ring during cytokinesis actin filaments Correct! Correct! Directly involved in muscle contraction actin filaments Correct! Correct! Supports and strengthens the nuclear envelope intermediate filaments Correct! Correct! Great work! 1 / 1 pts Question 4 Match the type of intermediate filament with its appropriate location. Vimentins connective tissue Correct! Correct! Keratins epithelia Correct! Correct! Lamins nucleus Correct! Correct!
