Semipermeable membrane

------ 1- a-They are found primarily in the thylakoid membranes. b-No. Cyanobacteria do not have distinct nuclei. c-Gloeocapsa ------------------------------------------------------ 2-They were much smaller by comparison. ------------------------------------------------------- 3- a-I think we decided in class to call them a brick prism. b-I recall the concensus was 2 layers at minimum. c-The cell wall surrounds the cell membrane and provides these cells with structural support and…

horror as a virion snuck up behind him and attached itself to Ugly poo’s backside of his membrane. “NOOO!!” he screamed, and without thinking got back up to try and help him out. The moment his back into the battle range he was bombarded by a group of virions. They attached themselves to his membrane and he collapsed to the floor of the Brachial Artery. He screamed in pain as the virus penetrated his plasma membrane and slowly took over his insides. It was a horrible way to die. Before the world…

How is the membrane structure related to the transport of materials across the membrane? The membrane structure plays an important role in the transportation of materials across the membrane. The Cell membrane is a barrier that separates a cell from its surrounding environment. This is composed of Phospholipids, Proteins, Cholesterol and Carbohydrates. The Membrane Structure has a very important role in the transportation of materials across the membrane. The membrane of the cell is made up of…

cilia and flagella found protruding from the cell body on the surface of eukaryotic cells are made of many microtubular bundles. Cilia are hair-like structures that protrude from the cells surface in eukaryotic cells they are covered by a plasma membrane. They are formed from a stable bundle of microtubules; these grow from an area in the cytoplasm called the basal body. Microtubules are made of a protein called tubulin, alpha has a slightly negative charge and beta has a slightly positive…

bacterium consists of a double membrane and is helically shaped (1). One of the membranes is an inner membrane and the other membrane is the outer membrane, also consisting of a protoplasm that is generally cylindrical and long. The most unique feature of the Borrelia burgdorferi is its ability to travel easily through its host’s fluids and tissues by using their highly adaptive flagella (2). The flagella in most spirochetes is found in the periplasm between the diderm membranes. It has a…

History All plants need water, but plants may prefer one type of water over another. There are two main types of water, tap water and rainwater, and each type of water has its pros and cons. Different plants need different amounts of water. Along with that, some plants also need water more frequently. This writing is going to explain about how plants prefer one type of water over another. There are many chemicals added to tap water. The uses of these chemicals is to disintegrate any dirt in the…

Membrane Potential in the RMP The membrane potential in the Resting Membrane Potential, or the RMP, is the little bit of voltage or electrical potential going across from the membrane of its regular resting voltage. This is caused because of gradients that make the ions go across the membrane of a cell through ion channels because ions are not soluble so they have to go through channels. These channels are called ion channels that are watery pores allowing ions to get through according to their…

blood plasma. This binding to the plasma proteins can play a significant role in determining drug distribution. This binding also plays a role in drug dynamics in that only the unbound or free drugs interact with the receptors and penetrate the cell membranes. Albumin along with others (i.e. lipoproteins, al-acid-glycoprotein) help with the binding process. As a result of this process, the drug that is bound is maintained in the blood stream while the unbound components are excreted or…

1) What is a difference between endotherms and ectotherms? The difference between an endotherm and an ectotherm is how their body is composed for regulating body temperature. This is important, as body temperature is key to maintain homeostasis. While ectotherms must rely on outside variables to regulate body temperature endotherms can regulate body temperature using mechanism within their own body. A major adaptation in endothermic organisms that is not seen in ectotherms is the large number…
