Enzymes are globular proteins that are synthesized by the ribosomes in a cell. They act as catalysts during biological reactions; therefore‚ enzymes are able to speed up these reactions without undergoing a permanent change themselves. These proteins are able to do this by lowering the activation energy of a reaction. To add on‚ enzymes require specific conditions under which they can work best. Reactions occur at faster rates when the temperature is higher. However‚ the rate of an enzyme-catalyzed

Microorganisms are classified according to their structure. By means of flow charts‚ diagrams and tables explain the differences between Viruses‚ Bacteria‚ Cyanobacteria‚ Achaea and Fungi. Bacteria or bacterium are unicellular microorganisms. They are essentially only a few micrometres long and form of various shapes including the spheres‚ rods and spirals.

Causes and Spread of infection (ICO2) 1) Infections are the result of the body’s inability to fight off microorganisms that can cause damage or disease if they are left untreated. They can be viral or bacterial in nature and might be caused by a fungus or parasite. There are many common types and there are some rare ones which all have varying causes and treatments. Common bacterial infections include strep throat‚ urinary tract infections and E. coli; the different types are caused by many different

LSD By Bix Lysergic acid diethylamide (or LSD for short) is an illegal potent hallucinogenic drug. History Albert Hofmann‚ a chemist working for Sandoz Pharmaceutical‚ synthesized LSD for the first time in 1938‚ in Basel‚ Switzerland‚ while looking for a blood stimulant‚ But its hallucinogenic effects were unknown until 1943 when Hofmann accidentally “ate” some LSD. It was later found that an amount as little as 25 micrograms (equal in weight to a few grains of salt) is capable

A ringworm is an itchy‚ contagious infection caused by a number of fungi‚ affecting the skin or scalp. One could get the infection from skin to skin contact‚ such as handshakes or hugs. One could also get it from touching a contaminated animal or object‚ such as dogs or a doorknob. The most common locations to find ringworms are the scalp‚ chest‚ hands‚ groin‚ and feet. There are many types of ringworms but here are some common ones: tinea corporis (skin)‚ tinea capitis (scalp)‚ tinea pedis (feet)

studying declines. In a study by Becker and Zamudio (2011)‚ they showed the associations between habitat loss and factors of disease. These factors include occurrence‚ prevalence‚ and infection intensity. The disease that was chosen was from a chytrid fungus‚ Batrachochytrium dendrobatidis (Bd). They studied the effects on amphibian populations in tropical regions. Habitat loss lowers species diversity by reducing natural habitats which increases population isolation and edge effects. There is also a

Collapse Most scientists theorize that one of the main reasons for the Colony Collapse is the use of pesticides. However others believe that there are other reasons that might help to harm the bees. These factors include immunodeficiency‚ mites‚ and fungus. Though no one has been able to prove a single cause of the Colony Collapse‚ scientists have made some strong theories. 6) Affecting humans The bees are very important to our daily life‚ as they do so much for us. Bee pollination is responsible
