Short answer essay: 1) Pancake-shaped cells explores the environment – moving filopodia with receptors extend from cell surface all over cell and “sense” environment. (1 point) 2) Then in some area filopodia stop moving due to signal received (biochemical cascade changes cell in that area). (1 point) 3) That area restructures to extend large, lamellipodium that pushes out against the plasma membrane; the mechanism causing this is a new network of actin filaments. (1 point) 4) When l...

In order to examine cells which are smaller than can be detected by the human senses, what needs to be used? (pick the best answer). 3. A normal cell is anchorage-dependent for growth and mortal. • 4. A single-celled eukaryotic organism: 5. In your own multicellular body, different cells in your body have a division of labor between them. • 6. In your own multicellular body, cel...

BIO353: Exam 2 Short Answers Module 11: Actin Filaments 1. Draw an actin monomer and an actin filament and label all the parts, molecular weights, etc.. 2. Explain the geography of actin filaments. Explain the geography of stress cable, filapodia and lamelliapodia in a cell, and locomoting in a culture plate. 3. Focusing on actin monomers and actin filaments: explain what occurs when a cell reverses its direction by 180 degrees. 4. Explain how the binding of ATP affects cytoskeletal monomers. Ex...

A cell that is itself an organism must have a minimum of four needs presented in lecture. List these four things: Write a few sentences that explain what limits an individual cell from becoming more complex. In Cell Biology what can limit the progress of science? A normal cell is anchorage-dependent for growth and mortal. Compared to bacteria which of the cell types below are not responsible for finding food? The paramecium discussed in class contained an organelle called the contractile vacuol...
