Hypothalamic programming of systemic ageing involving IKK-b, NF-kB and GnRH (Zhang et al., 2013). Cellular senescence is when a cell’s replicative mechanism becomes arrested. This was phenomenon was first described in Hayflick’s experiment. Cellular senescence is usually due to protect the cell from becoming cancerous but it also plays a prominent role in aging (van Deursen, 2014). While senescence describes a halt in proliferation, cancer development is the uncontrolled proliferation of…

enzyme’s functionalities by using the enzyme called catalase. Catalase helps break down hydrogen peroxide, the substrate, to water and oxygen, the products. To illustrate its effectiveness “Catalase prevents the accumulation of and protects cellular organelles and tissues from damage by peroxide... In mammals, catalase is found…

Ca2+ ions from the cytosol of muscle cells in the heart. SERCA2a acts like a pump that sits on the edge of the sarcoplasmic reticulum and protrudes out into the cytoplasm of the cell (Hajjar & Njeim, 2010). The sarcoplasmic reticulum (SR) is an organelle that is unique to muscle cells. Its primary purpose is the storage, release, and reuptake of Ca2+ ions from the cell’s cytosol, and this in turn provides the basis for muscular contraction and relaxation. SERCA2a pumps are responsible for…

parts such as, a nucleus which is like a brain, and mitochondria which give them energy, and many other things. Also, like I was trying to say before, one difference between Archaebacteria and Eukaryotic bacteria is Eukaryotes have membrane-bound organelles.” she finishes. Both of the cubs seem to understand but she wants to make sure so she asks them,”Any…

damage on it due to the red color of the solution. . Betacyanin is the red pigment that is contained inside the beet cell membranes; they are also water soluble (Neelwarne, 2012). Since the cell membrane is the structure that separate the cells organelles from the extracellular matrix; when the membrane is damaged, the fluid that is inside the cell can leak out (Gupta,…

INTRODUCTION Microbes are those microscopic organisms that can cause diseases in the human body. These microbes migrate with locomotive organelles called FLAGELLA, a very vigorous nanomotor that is highly conserved across bacterial species. Flagella allow the microbes to move towards favourable environments. Further studies on flagella has revealed that it not only serves the purpose of locomotion but also plays a very crucial role in bacterial pathogenicity(14). A flagella has mainly three…

DNA is a macromolecule that is used for instructions when creating proteins and other activities. It is because of this that DNA (and other nucleic acids) are essential for life to exist. DNA contains genetic code that primarily directs organelles in a cell to operate in a certain way. DNA also carries information regarding the traits of an organism. These traits are often passed from a parent cell to its offspring. This branch of biology is know as genetics. DNA also possesses a unique…

The buccal cells observed are therefore eukaryotic epithelial cells with the presence of the nucleus along with a cell membrane that depicts the outer boundaries of the cell and the cytoplasm, a translucent like fluid encompassing the cells organelles. Conclusion Exposing myself to the laboratory has provided valuable insight on microscopy. I have garnered a better understanding of the capability of the microscope to enhance the image of microscopic structures. This was an evidence based…

It's my senior year of high school, and, along with my fellow classmates, I'm preparing to be thrown out into the “real world.” While, I have gathered plenty of knowledge about cell organelles and the Pythagorean theorem over the course of my high school career, I seem to be lacking a comprehension of basic life skills. This is a major problem! When I came to this realization, I began discussing the issue with some of my fellow classmates. They agreed that they are in the same predicament. We…

Introduction: IPL, Intense Pulsed Light, is a relatively new medical technology that awards itself of being a source of bright pulsed energy that, is neither one-color nor clear, but rather has got a wide-ranging wavelength spectrum. IPL can be adjusted to different wavelengths to fit all the tones of colors, making it ideal to use on a wide array of different skin tones. These colors are modified by crystal filters that function as trimmers and allow the selection of precise wavelengths for…
