The effect temperature has on the activity of the enzyme α- amylase. Introduction Enzymes are a biological catalysts‚ which means that they speed up the chemical reactions in living organisms. Almost all of enzymes are energized protein molecules that catalyse and regulate nearly all biochemical reactions that occur within the human body. The reason in which enzymes are sensitive to heat‚ pH and heavy metal ions is because they are made up of proteins. The food we eat is turned into energy by enzymes

Liquid-Vapor Phase Diagram Abstract: Liquid-vapor phase of acetone/chloroform was studied through distilling a series of mixtures with different mole fraction. When the mixtures were boiling‚ their vapor was condensed through a water column and collected in a receiving container. Refractive index was collected for starting mixture‚ distillate and residue for each sample. A boiling temperature versus acetone’s mole fraction was constructed to show the liquid-vapor phase diagram. The boiling temperature

Would you want to enlist when there’s death and illness‚ harsh conditions‚ and lack of support and supplies? I think not. In war we all know it’s not easy‚ but we all don’t know it was that hard. Most armies have supplies‚ support‚ and become stronger as one‚ but no not this one. I would not enlist because of the conditions they serve‚ and the army is not as strong as others are. Why would I want to enlist when there’s death and illness involved? In Document A it shows the numbers of deaths in

Has technology helped us?” No Matter where we turn in the world‚ technology has become a part of our daily lives. We can find technology in businesses‚ hospitals‚ schools‚ communities and pretty much everywhere we turn. Some argue that we are too dependent on technology and as a result we have become isolated rather than more sociable; an example would be our newest generation of children that spend countless hours playing by themselves video games‚ computer games or sitting in front of a TV

The V-n diagram usually focuses on both positive and negative loads‚ however since there is little knowledge known about the box wing‚ for simplicity‚ the positive loads are assumed to be more significant. Hence‚ if the box wings are optimised with the positive loads‚ the negative loadings will also be covered due to its least significance. The 3.5g pull out of dive is known as the most extreme load which is closest to critical pressures for distortion‚ as shown in figure (3.4). Hence using this

how living organisms look or work. They also control the manufacture of proteins in a cell. There are about 35 000 genes found in almost every healthy cell. Scientists are constantly conducting experiments on genes. Genetic modification is one of such experiments. Genetic modification refers to the deliberate alteration of the genetic structure or DNA of an organism in order to give it new abilities and produce a desired effect. Organisms that are modified with DNA from another organism are called

How are organisms adapted for efficient gas exchange? [25 marks] Many organisms have different features which enable them to survive and carry out gas exchange effectively. Single-celled organisms‚ such as bacteria and protozoa‚ are in constant contact with their external environment. For them‚ gas exchange occurs by diffusion across their membranes. Even in simple multicellular organisms‚ such as green algae‚ their cells may be close to the environment‚ and gas exchange can occur easily. In
