immune system
The best answer would be Antibodies; however, these do not chemically "attack" viruses or bacteria. More accurately, antibodies recognize various germs and allow the various cell types of your immune system to attack and destroy these germs directly. For more info on how this works see: http://en.wikipedia.org/wiki/Adaptive_immune_system
All bacteria produce chemicals. Could you possibly be more specific?
The immune system is stimulated to produce antibodies that can target and destroy viruses and bacteria when the body detects an infection. This immune response helps to neutralize the pathogens and prevent them from causing harm to the body.

The two structures that produce chemicals that can kill bacteria are lysosomes and peroxisomes. Lysosomes contain enzymes that can break down bacterial cell walls, while peroxisomes produce hydrogen peroxide, which has antimicrobial properties.
The immune system simulates the body to produce chemicals such as antibodies, interferons, and cytokines that help destroy viruses and bacteria. These chemicals work together to identify and neutralize pathogens to protect the body from infections.
Bacteria on your skin can grow in the salty dampness of perspiration, especially in poorly ventilated areas of the body. The bacteria produce chemicals that smell bad.
Less then 1 percent cause disease. Disease causing bacteria produce toxins- powerful chemicals that damage cells and make you ill.
Chemosynthetic bacteria means bacteria that can make chemical things (synthetic). Basically any bacteria are chemosynthetic - they all product different chemicals as part of their metabolism. There are methanogens that produce methane gas, there are photosynthetic organisms that produce oxygen (like plants, and the ancestry of plants), others can produce nitrogen gas, like those bacteria that live in nodules on legume plants. Other bacteria can produce acids from fermentation like proprionic acid which gives Swiss cheese its nutty flavor. So lots and lots of bacteria are chemosynthetic. It just depends on what you want to produce.
Green plants and some bacteria can capture energy from sunlight and chemicals respectively.
Follicle stimulating hormone stimulates the gonads to produce gametes. It is sometimes abbreviated FSH.
