BSC 515, A Cell Bio Problem Set 1 Q1. In 1944, at the beginning of his book What is Life, the great physicist Erwin Schrodinger asked the following question: â€Å"How can the events in time and space which take place within the spatial boundary of a living organism be accounted for by physics and chemistry? What would be your answer today? Living organisms contain molecular and cellular machinery that maintain homeostasis. All of this machinery is governed by the laws of Physics and Chemistry and with our increased understanding of the biological sciences we understand the complex relationship of all three of these sciences in living systems. Each science is inherently dependent on another: BiologyïÆ'   ChemistryïÆ'   PhysicsïÆ'   Mathematics. Do you think there are peculiar properties of living systems that disobey the laws of physics and chemistry? Chemistry and Physics are our understanding on how the natural laws and forces are at work in our Universe. If these laws are considered Universal then they would govern living organisms as well, therefore it would be near impossible for living systems to disobey any of these fundamental properties. Q2. Cell growth depends on nutrient uptake and waste disposal. You might imagine, therefore, that the rate of movement of nutrients and waste products across the cell membrane would be an important determinant of the rate of cell growth. Is there a correlation between a cell s growth rate and its surface—to—volume ratio? There is a directShow MoreRelatedUse Of Bio Printers As A Replacement For Current Organ Donation Treatments1442 Words   |  6 Pagespotential use of bio-printers as a replacement for current organ donation treatments was investigated. The current organ situation in Australia was explored to assess whether the implementation of bio-printing was suitable. It was discovered that more than 1,500 people are on the Australian organ transplant waiting list, and was thus concluded that bio-printing technology could assist in reducing stress on the waiting lists. Further, this investigation involved researching various bio-printing methodsRead MoreBio 135 Test Review Essay1396 Words   |  6 PagesBIO 135 Test 3 (6,7,8,16) Review Sheet 1.

Introduction to Bio-Oil and Algae strains Bio-Oil is an organic fuel that contains energy that is made from natural living organisms. They are produced from lipids which are merged with other ingredients which chemically produces Bio-Oil. Fossil fuels are generally easier to harness but it is produces a lot of carbon emission which is greatly detrimental to the health of the environment. Thus, the idea of Bio-fuel is introduced asRead MoreBiological Treatment Of Oil Spills : Biological Treatment Of Oil Spillss1353 Words   |  6 Pagesnutrient or enzymes that enhances the rate of bio-degradation of oil spills. It is the process of digestion of oil spills through microorganisms such as fungi, bacteria, yeasts, etc., it is a simple process of breaking f complex compound to form simpler molecular giving out energy and nutrients. Bio-degradation of oil is a natural process that takes place over a long period of time (days, weeks, months or even over years) to degrade oil from the water. Bio-remediation is a technique of adding mattersRead MoreWhat is Cancer?1249 Words   |  5 Pagesgenerally found. It constitutes a dense arrangement of cancerous epithelial cells commonly in small form, penetrating glands with a symmetrical de-crease in stromal volume [2]. B. Lee et al. [3] used tissue bio-impedance to differentiate between the diseases because morphological differences between normal and malignant prostate tissue are present and sensitivity of electrical im-pedance spectra to cellular structure was known. Bio-impedance is one of the properties referred to a tissue’s re-sistance whenRead MoreEmbryo Based Stem Cell Research1171 Words   |  5 Pages Embryo-based stem cell research The controversy concerning the ethical dilemma related to stem cell research rages on. One particular basis of this controversy emanates from the fact that embryonic stem cells research derives its stem cells from destroyed embryos. Stem cells are cells that are yet to be specialized into specific tissue that serves specific function in the organism. Some radical scientists have labeled these cells the building blocks of future medical and biotechnical researchRead MoreChemistry : Biology And Chemical Biology1099 Words   |  5 Pagesprotein activity and identify protein interactions within living systems.(Singh et al., 2016) Types of reactions that fit this definition are as follows 5.1 Condensations of Ketones and Aldehydes with Heteroatom-bound Amines Historically, the first bio-orthogonal ligations involved ketone–aldehyde condensation reactions. While ketones and aldehydes can form reversible imine adducts with many amines found in biological systems, this process is thermodynamically unfavourable in water. This led toRead MoreBiological Therapy Case Study830 Words   |  4 Pagesshown that injection of growth factors can reduce the expression of inflammatory cytokines in degenerative intervertebral discs. Biologically active substance injection: for early intervention of intervertebral disc, can promote cell proliferation within the disc, promote cell matrix synthesis, which can theoretically reconstruct the height of the intervertebral space. The types of active substances include transforming growth factor-ÃŽ ² (TGF-ÃŽ ²), epidermal growth factor (EGF), basic fibroblast growthRead MoreBio 312 Immunology Final F16994 Words   |  4 PagesBIO 312 Immunology Final F16 1. What protein/antigen marker would someone use for flow cytometry /FACS analysis to sort out hematopoietic stem cells? The best protein to use is CD34 because it is present on all human hematopoietic stem cells, anti-CD34 monoclonal antibodies are often used to separate the hematopoietic stem cells from other bone marrow cells. 2.
