What are the nonpolar parts of a phospholipid? c. Tail group 4. This is the only polar portion of a cholesterol molecule and it forms hydrogen bonds with the polar heads of phospholipids. d. –OH group 5. This type of membrane protein will extend throughout the entire membrane touching both the Intracellular fluid and the Extracellular fluid. e. Integral proteins f. Transmembrane proteins g. Integral proteins and Transmembrane proteins Ans: D…

Bacteria They are formed by a single rudimentary cell. They have no nucleus or plastids, but chromatin. Some have assimilators pigments. They are on earth, water, and air, and can generally move. They may be causing disease and therefore are called pathogens. Those that do not cause disease are called saprophytes. In some cases, they are even useful, as in digestive processes or synthesis of vitamins. By the way, they are called coconuts when circular; bacilli if they have the form of rods;…

propagated form synaptic inputs are summated before being transmitted to the axon. The structure of the initial segment is made up of three things: a dense layer of finely granular material undercoating the plasma membrane, scattered clusters of ribosomes, and fascicles of microtubules. 2. A collateral axon is a branch off the main axon that usually feeds back onto the soma. This function provides modulation of cell firing. 3. Axon terminals are distal terminations of the branch of an axon.…

I put that aside for a minute as I helped make dinner with the family. “Family…..family.” Thinking to my I tried to figure out what that had to do with the cell, then I got it! My family is like the ribosomes, they make protein for the cell like my family make food for us. While I was in the kitchen I thought about the vacuole and how it stores all of the food and waste for the cell. “What is like the vacuole?” I thought to myself. “I know, the fridge…

clinical trials have led to its indication for the treatment of ABSSSIs in adult patients with susceptible bacteria.1 Tedizolid phosphate is a prodrug that is converted by plasma phosphatases to its active form. It interacts with the bacterial 23S ribosome initiation complex and binds to the 50S subunit to…

a circular DNA, with genes in the DNA encoding specific proteins that contribute to the form and function of the cell. These proteins are planned by using the base-pair blueprint from the DNA, where it is then transferred from the nucleus to the ribosomes to be translated and chained together with amino acid sequences.4 E. Coli is the most widely studied prokaryotic organism in part due to the rate at which E.Coli. can grow, and also due to the fact that it has the ability to transfer DNA…

Abstract: Serratia marcescens, which two decades ago was considered a harmless bacterium, is causing infections that are becoming progressively difficult to treat with antibiotics. These bacteria have grown resistant to certain antibiotics and in this experiment, we tested how S. marcescens reacted to 6 different antibiotics. My colleagues and I swabbed a mixture of nutrient broth and Serratia marcescens onto an agar plate containing 6 antibiotic tablets and let the plate sit for a week. We then…

component. For example, the structure of the mitochondrion defines the key function that it will play out. The matrix is the cytoplasm in the mitochondrion, or the fluid contained inside the inner membrane, providing a watery substance that contains ribosomes and many enzymes. Those enzymes are also vital for the link reactions and the Krebs cycle to helps the mitochondrion’s function. The inter-membrane of the mitochondrion is the space between the inner and outer membrane and its function is…

Even though systematics previously used more conventional systems such as Chatton’s division of life in to two main cellular groups; the eukaryote-prokaryote dichonomy (cited in Sapp, 2005), as well as Whittaker’s Five Kingdom system to organise all living things (Whittaker, 1969), they do not co-exist compatibly or correctly. The five kingdom system is not phylogenetically correct and eukaryote and prokaryote systems do not take into consideration new sequencing abilities (Kandler, Wheelis &…

Life is recognized by what we do. People, animals, plants and insects encompass properties such as order, regulation, growth and development, processing energy, responding to the environment, reproduction, and evolution. All living organisms exist with nonliving factors, as such, their interactions form an ecosystem. The two main processes of an ecosystem are the recycling of chemical nutrients and the flow of energy. Cells are a component of all living organisms and essentially are life’s…
