1 Diffusion is the movement of molecules (or ions) from a high concentration to low concentration. Diffusion is form of passive transport as energy does not need to be generated. Diffusion is complete when the concentration of molecules is equal on either side of the membrane. Diffusion rate can be influenced by many factors such as: Concentration gradient across the the membrane. Permeability of the membrane to the diffusing substance. Temperature. Surface area of the membrane. Question 2 2.1

Bacterial Fermentation Secondary article Article Contents Volker Mu¨ller‚ Ludwig-Maximilians-Universita¨t Mu¨nchen‚ Munich‚ Germany . Introduction Under anaerobic conditions‚ in the dark and in the absence of electron acceptors‚ organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions‚ a process called fermentation. In fermentation‚ the organic compound serves as both electron donor and acceptor‚ and adenosine

Bacteria are unicellular and ultra-microscopic organisms‚ yet they play an important role in nature. They are of tremendous importance to man. They play an important role in agriculture and medicine and are the basis of many industries. Some are beneficial to man directly or indirectly‚ others are very harmful as they cause various plant and animal diseases. Bacteria are considered as our friends and foes due to their beneficial and harmful activities. Their economic importance can be studied under

Identifying the Unknown Bacteria: Bacillus cereus Brittany Moy Coastline Community College Abstract Bacillus cereus is a Gram-positive‚ facultative aerobic‚ spore-forming‚ rod-shaped bacterium that is widely distributed among the environment. Introduction The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria
