venlafaxine (brand name: Effexor) A medication used to treat depression (antidepressant) that affects chemical messengers within the brain. These chemical messengers are called neurotransmitters, and some examples are serotonin, dopamine, and norepinephrine.
They form an endospore. An endospore is a thick cell wall that helps protect them. Endospores enable bacteria to lie dormant for extended periods of time when the environmen â¦ t is unfavorable (such as extreme temperatures, radiation, extreme pH levels, extreme pressures and harmful chemical agents).
1 Water -- Bacteria need water to dissolve the food they use for energy and growth. 2  Water allows the food to get into the cells, is used for the many chemical reactions necessary for life and growth, and allows waste products to escape.3  Food/Nutrients -- All bacteria require energy to live and grow. Energy sources such as sugars, starch, protein, fats and other compounds provide the nutrients. 2  Oxygen -- Some bacteria require oxygen to grow (aerobes) while others can grow only in the absence of oxygen (anaerobes).
