Test Tube Degrees Celsius
1,267 wordsEnzyme Action: Testing Catalase Activity Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon, however enzymes will only lower the energy of activation for specific organisms, reducing chaotic chemical reactions. The reaction is carried out in its entirety in the active site of the enzyme. The substrate (organism acted upon), binds itself into the active s...

Side By Side Endoplasmic Reticulum
2,193 words... e detoxification processes by which enzymes act on chemicals and drugs to change their structure and reduce their toxicity. The smooth endoplasmic reticulum of skeletal muscle stores calcium ions that function in muscle contraction. The Golgi apparatus is composed of flattened membranous sacs, containing cisternae, that are stacked on each other like dinner plates. The Golgi apparatus modifies, packages, and distributes proteins and lipids manufactured by the rough and smooth endoplasmic ret...

Rate Of Reaction Bunsen Burner
1,230 wordsInvestigate A Factor Which Affects the Rate Of Fermentation Of Yeast This experiment is investigating one of the factors which affects the rate of fermentation of yeast. Several factors affect the rate of reaction: &# 61656; Increasing the concentration. (See the lock and key theory. ) If the substrate (glucose) is increased, then there would be more keys for the locks, therefore an increase in reactant concentration leads to an increase in reaction rate. &# 61656; The surface area, the bigger t...

Rate Of Reaction Carbon Dioxide
1,229 words... onward sources, from a textbook, encyclopedia, and preliminary work that I have done in class. I have shown my results on a bar chart and a line graph. On the line graph, I have drawn a curve of best-fit. There were no anomalous results. From my results, and my graph, I have found out that as the temperature of the enzymes (yeast in this case) is increased, the rate of reaction speeds up. However, when the temperature reached a certain point, (about 40 degrees Celsius), the enzymes became de...

Source Of Energy Amino Acids
1,317 wordsThe topic I have chosen is Osteoporosis and how it is related to a deficiency of calcium. Throughout my human nutrition course the importance for proper nutrition and adequate dietary supplements has been constantly emphasized. Nutrition is the science that deals with food and how the body utilizes it. All living things need food to live. Food supplies energy, which people need to perform certain actions and bodily functions. Food also provides substances that the body needs to build and repair ...

Endoplasmic Reticulum Organic Molecules
1,136 words... m is used to breakdown glycogen to glucose. The endoplasmic reticulum is versatile and grows and shrinks according to the cell's activities. Chloroplasts which are found in plant cells are used in the process of photosynthesis. They fall into the category of plastids but they are differentiated in that they contain chlorophyll. These organelles produce chemical reactions from the energy that the sun gives them. The Golgi complex's structure is made up of many flattened membranes sacs that ar...

Chemical Reactions Three Types
890 wordsChemical Chemical Reactions CHEMICAL REACTIONS Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named George Ernst Stahl was the first to speak of chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the ai...

Atomic Theory Chemical Reactions
379 wordsAtomic Dalton Theory Dalton s Atomic Theory John Dalton developed the first useful atomic theory of matter around 1803. In the course of his studies on meteorology, Dalton concluded that evaporated water exists in air as an independent gas. Solid bodies cant occupy the same space at the same time, but water and air could. If the water and air were made of discrete particles, evaporation might be viewed as a mixing of water particles with air particles. He performed a series of experiments on mix...

If there is enough time to consider a second variable however, the effects of a temperature or alcohol on the daphnia's body system will also be considered alongside the initial variable of caffeine. These will then be slotted into the same graph which will show us how the figure correspond to the results. In order ...

This is because ecological imbalances were as a result of the Industrial revolution, which could be said to be the beginning of the non-ending technological advancement cycle. During Industrial revolution, we began altering or climate and environment through changing agricultural and industrial practices. Before the industrial revolution, human activity released very few gases into the ...

Carbon Dioxide And Water H 2 O
640 wordsThis paper is on the processes of fermentation, cellular respiration, photosynthesis, diffusion, osmosis, and enzyme activity. What do these six processes have in common? Fermentation is a chemical process that breaks down organic materials. This process is carried out by such microbes as bacteria, molds, and yeasts. For example, molds or fungi act upon mixtures of molasses and mineral salts to produce penicillin. Yeast breaks down sugar gotten from malted grain into ethyl alcohol and carbon dio...

807 wordsToday, weve realised that the very first life on Earth was indeed originated from abiotic surroundings. In fact, organic molecules have been successfully generated from abiotic elements by scientists To understand how this creation of life from abiotic material occured, we have to consider a critical idea. Life originated from its abiotic surroundings. Thus, it is important for us to learn about the physical and chemical environments of the primitive Earth. The atmosphere of primitive Earth cons...

The average human being spends one third of their life in sleep and during each sleep approximently two hours is spent dreaming (Ullman and Zimmerman 1979). These dreams are important because they are the voice of our subconscious. Dreams and theories on dreams go as far back as 2000 BC in Egypt. One of the first org...
