Biology Unit 1 – Section 3.1.1 Microorganisms as Pathogens To be considered a pathogen it must: Gain entry Colonise the tissues Resist the defences Cause damage to the tissues Pathogens include bacteria‚ viruses and fungi How do microorganisms enter the body Many pathogens enter through the gas exchange system (including ones that cause flu and TB) Food and water can carry pathogens into the stomach and intestines via the mouth and into the digestive system (including

photosynthesis. The oxygen released in the air can be used by organisms that respire aerobically to release energy stored in molecules‚ these organisms release water and carbon dioxide as a byproduct. The carbon dioxide is necessary for the synthesis of carbohydrates in the organisms. Cellular respiration can be defines as metabolic reactions in organic cells which converts

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

support my hypothesis. The results showed glucose did ferment the easiest‚ but it was followed by sucrose as opposed to fructose‚ fructose was after sucrose then the starch. Luckily‚ my test control did work as expected. This experiment proved that yeast depends on glucose as its’ main source of energy. This happens when glucose is reduced to pyruvate which leads to the fermentation of carbon dioxide and ethanol. The hypothesis that I tested with the soybeans was “Cellular respiration is higher

Fig. 20-10 * MPF is a kinase that phosphorylates many different substrates to initiate mitotic events * To exit mitosis‚ MPF must be destroyed * Destruction of MPF depends on the destruction of Cyclin B * Destruction of Cyclin B is via the ubiquitin pathway * Ubiquitin is covalently linked to
