GENETİCS DATE OF EXPERIMENT: 02.03.2011 ABSTRACT In this experiment‚the cell growth of yeast is measured by using spectrophotometer and hemocytometer.We learnt how specthophotometer and hemocytometer use and also we learnt qualifications of hemocytometer and spectrophotometer.Serial dilution was used for this experiment and it was very important.Because of the serial dilution‚we measured the number of yeast cells. The graph of growth curve was drawn and bacterial life cycle was understood with the

VITAMIN A - (retinyl palmitate‚ beta-carotene‚ lutein‚ lycopene‚ mixed carotenoids) POTENTIAL BENEFITS: Helps support bone formation and cell membranes. It’s important to support the eyes‚ hair‚ skin and teeth. In other words‚ Vitamin A stimulates growth and vitality. It helps form the colour purple which is essential for night vision. It’s great for immune system functions - like fighting infection‚ colds‚ flu and bacteria. It also helps maintain the healthy function of the reproductive organs

solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then it will break down the peroxide faster because yeast tends to rise faster as the temperature increases. Some constants in this lab are: the 10 mL of peroxide‚ the 190 mL of water‚ the same timer‚ the same sheet of filter paper and the

Recent research shows that the highest incidence of cancer among men is prostate cancer. The numbers are alarming‚ however‚ one thing that can be reassuring is that this kind of cancer can be prevented by making some lifestyle changes and changing your diet by eating the right kinds of food‚ keeping weight controlled and having an active lifestyle. Prostate cancer prevention is possible by doing some of these simple changes that may seem difficult at the start‚ but provides a lot of benefits in the

be the pinnacle of craftsmanship and skill. It is a bread that is quite tricky to make and even more tricky to do well. This is because every aspect of the bread is from scratch‚ most importantly the yeast used in its production. When making sourdough‚ the baker must grow and cultivate their own yeast cultures in order to make the bread rise. It is through this process that more control is given‚ and this allows for better quality bread. This is the essence of making sourdough. The idea that the quality

RAW MATERIALS The main ingredients of which the main good is produced are flour‚ salt‚ water‚ yeast. Flour is the base of any type of bread. It can be wheat one or rye one. Depending on milling one differentiates three sorts of rye flour‚ which is used in bread-making: usual (it has dark color with high content of cutoffs)‚ peeled (with grayish shade)

sucrose‚ startch‚ and fatty acids. The process varies depending on the fuel the cell is using. This report will show these differences by exopsing the yeast to several different conditions. The rate of the fermentation can be tracked by noting the carbon dioxide production at steady intervals. This lab followed the production of carbon dioxide by yeast fermentation in four types of solutions: one control group which contained no sugar‚ the next which contained glucose‚ the next with starch‚ and with

The two types of fermentation that are well known are alcoholic fermentation as well as lactic acid fermentation. Fermentation is vital for many organisms‚ such as yeast and bacteria‚ because it allows them to obtain energy required to carry on life processes. Alcoholic fermentation is especially important for human beings‚ as it is used to produce alcoholic beverages‚ bread‚ and many other everyday items that are

Enzymes An enzyme is a protein used to speed up the rate of a chemical reaction. Because they regulate the rate of chemical reactions‚ they are also called catalysts. There are many‚ many different types of enzymes‚ because for each chemical reaction that occurs‚ an enzyme specific to that reaction must be made. To act on a substrate‚ an enzyme must contain an active site. The active site is the area on the enzyme that allows the substrate and enzyme to fit together. The amino acids that are present
