Biology coursework: Substrate specificity in yeast AIM: To find out which substrate (glucose‚ starch‚ maltose‚ sucrose or lactose)‚ does yeast‚ the organism containing the enzyme‚ breaks down the quickest. Introduction: Usually‚ every enzyme has a specific substrate that is what we call the “lock and key” theory. We can try the reaction of an enzyme with different substrates and this enzyme will just work well with one of those substrates. One type of reaction catalyzed by enzymes is anaerobic respiration

#2) Both Winner and Joy explore the issue of technology and control. How would you compare their two views of current technological development? Focus the comparison on a specific technology‚ such as genetically modified organisms. Technology is always in need of control. You cannot have a world that technology is in control such as the movie Terminator‚ where technology takes over. Just like human beings there is always a need for control. Both Winner and Joy explore this topic; Joy believes

MODIFIED ORGANISM SAY NO TO GMO WHAT IS GMO?? DISADVANTAGES OF GMO?? Environmental Impacts used to enhance a more common food crop‚ such as corn‚ it might introduce a similar allergen which could have a severe health impact to the consumer. An alteration to a certain plant might make it inedible or harmful to another organism such as an insect that relies on it for food. It can harm organisms that are desirable or can upset the balance of the food Organisms that have been

Amongst many problems that living organisms face‚ one of the biggest is the change in the temperature of the environment. Why is this a major problem for living organisms? A change in the temperature of the environment disrupts many of the body’s enzymes and regulatory proteins‚ changing their shape and perturbing their function. However‚ organisms have taken two different approaches to tackling this problem we call this organisms endotherms and ectotherms but in this essay‚ we will talk about an

different species of living organisms‚ bacteria‚ or viruses to get desired traits such as resistance to disease or tolerance of pesticides. How do scientists Genetically modify organisms? Genetically modifying organisms works just like an advanced form of cut and paste. During genetic modification‚ DNA is taken from and unrelated plant‚ animal or bacteria and inserted into a different organism to get it to produce the desired traits. The DNA is“cut” from one organism and “pasted” into and unrelated

about vector organisms such as ticks and mosquitoes and ways to remove them. Vector Organisms and the Diseases They Carry Vector organisms are parasites that transmit various diseases. Two vector organisms are ticks and mosquitoes. These two vector organisms transmit many well-known diseases. Through most of this essay‚ I will be explaining these two different organisms and the diseases that they carry. First‚ I will be explaining deer ticks. Ticks are small spider-like organisms that attach themselves

The importance of carbohydrates in living organisms Carbohydrates contain carbon‚ hydrogen and oxygen in the ratio of 1.2.1.. There are many different types of carbohydrate‚ all of which are useful to living organisms. The most important carbohydrate is probable glucose. Glucose is a monosaccharide and is the monomer unit which makes up more complex polysaccharides. Two glucose molecules can be joined in a condensation reaction‚ whereby water is removed‚ for example to produce maltose‚ a disaccharide

living organisms‚ the solvent (water) would have net movement across a selective permeable membrane. Osmosis only occurs when a membrane such as that of a cell is permeable to water molecules but not to specific solutes (Tortora & Derrickson 2014). Certain simple molecules such as oxygen‚ water and carbon dioxide can travel across the cell membrane by osmosis‚ a passive process similar to other forms of diffusion (Hill 2007). Not merely is it vital to several processes in living organisms‚ it also
