science in which all the other sciences are based. In biology you learn about living organisms and their composition. Organisms are alive because of chemistry - Why we breathe oxygen‚ how we make energy‚ elimination of waste products‚ cellular respiration‚ etc. All of these are based on how living organisms use chemistry to live. Biological organisms have chemical compositions. Carbon is found in all living organisms. After that‚ because there are many chemical processes occuring in various living

yeast undergoes alcohol fermentation in order to continue ATP production but also to recycle NAD+ that is needed for glycolysis. Without this recycling‚ glycolysis and therefore cellular respiration cannot proceed and organism will die. o How efficient is fermentation- 2% (2 ATP) efficient compared to aerobic respiration‚ which is 39% (36 ATP) efficient at capturing the energy released in the form of ATP o What amylase does to starch- Breaks down starch to individual glucose units o What gas is produced-

Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric

Objectives for Lecture 9 Know the difference in resolution and magnification between light and electron microscopes. Understand the process of cell fractionation based on centrifugation and know what the purpose of cell fractionation is. Know what the differences in cell structure are between prokaryotic cells and eukaryotic cells Know that most eukaryotic cells are between 10-100 m in diameter‚ whereas most prokaryotic cells are about 1 m in diameter. Know the following terms‚ plasma

rate than if you are doing the contractions as fast as you can. The science backing up my hypothesis: The higher the intensity of any type of exercise the more lactic acid is produced in a certain amount of time‚ this is by a means of anaerobic respiration. Glucose+ Oxygen = Carbon Dioxide+ Water. Equipment: plastic or wooden pegs. – Because the exercise isn’t too strenuous on the body and it is a reliable way to showcase the toll of muscle fatigue. Stopwatch. – To record the time it takes for

perform better in mathematical tasks‚ if there was an increase in blood flow through exercise. The increase in blood flow should help the brain to perform better as it receives more oxygen. This is because all cells require oxygen for cellular respiration. To test this‚ three females‚ aged 16-17‚ were asked to answer four mathematical questions for four trials. As each trial progressed‚ subjects had to run on the spot for an extra 30s. It was clear from the observations that initially‚ the increase

If temp gets too high enzyme activity will diminish and the proteins. Cycles of freezing and thawing can denature proteins. Oxygen concentration: The paradoxical nature can be both toxic and essential to life. Obligate Aerobes rely on aerobic respiration for ATP and they use oxygen as the terminal electron transport chain. Microaerophilic require O2 from growth but they are damaged by normal atmospheric levels of oxygen and don’t have efficient ways to neutralize the toxic forms of oxygen such as
