There are types of cytoskeleton fiber- intermediate filaments. Tell their structure and/or function.

Gap 1. Actin Intermediate Filaments 2. Keratin Desmosome 3. Tubulin Microtubules 4. Proteoglycans 5. Connexon Microfilaments 6. Cadherin ECM

Collagen is produced as procollagen and then processed to collagen extracellularly. What would happen if procollagen was processed within the cell?

A triple helix filament structure is highly characteristic of:       a. Microtubules     b. Actin microfilaments     c. Collagen   d. Keratins

. Define centriole, microtubule, cytoskeleton, and axoneme.How are these structures related to one another?

Describe cellular processes which involve the coordination of cytoskeletal elements.

Which of the following describes an F-actin microfilament?     A flexible, helical filament composed of two strands assembled from G-actin     13 protofilaments composed of heterodimers with a hollow core     a flexible filament composed of 13 interwoven protofilaments     Eight tetramers twisted into a rope-like filament

can microtubule replace actin filament？why or why not？

Which of the following is NOT a way intermediate filaments are unique compared to the other cytoskeletal filaments? intermediate filaments rely on accessory proteins for their function intermediate filaments can be found inside the nucleus intermediate filaments are made from fibrous protein subunits intermediate filaments do not have structural polarity O intermediate filaments do not interact with motor proteins

Lysosomes are similar to what in plant cells? nucleus, chloroplasts, cell wall, Golgi apparatus, or vacuoles?
