Prokaryotes – Plasma Membrane as a Barrier _________ Is the diffusion of water across a semi-permeable membrane. Environment surrounding cells may contain amounts of dissolved substances (solutes) that are… - equal to - less than - greater than …those found within the cell.

Plasma Membrane as a Barrier _______________ TRANSPORT How most molecules move across the plasma membrane. Analogous to a pump moving water uphill. Types of active transport are classified by type of energy used to drive molecules across membranes. ATP Driven Active Transport Energy from adenosine triphosphate (ATP) drives substances across the plasma membrane with the aid of carrier molecules.

___________ is a huge polymer of interlocking chains of alternating monomers. Provides rigid support while freely permeable to solutes. Backbone of peptidoglycan molecule composed of two amino sugar derivatives of glucose. The “glycan” part of peptidoglycan: - N-acetylglucosamine (NAG) - N-acetlymuramic acid (NAM) NAG / NAM strands are connected by interlocking peptide bridges. The “peptid” part of peptidoglycan.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
