nutrients are absorbed in the digestive system
The cells that lines the GI Track into the bloodstream
The gastrointestinal tract, or GI tract.
Nutrients are absorbed throughout the digestive process. Specific nutrients are absorbed in the stomach and large intestines, but the majority of nutrients are absorbed in the… small intestines.
It eats the salt you eat
Most bacteria consume things already dead. They decompose stuff like shed skin, carcasses, and plant bits such as leaves. These do it by secreting digesting enzymes outs…ide themselves onto the food source. The bacteria then absorb just what they need. http://www.everything2.com/index.pl?node... Other bacteria can photosynthesize. These include the cyanobacteria that produce oxygen for our atmosphere. They still contribute up 30% of the Earth available oxygen every year. Then there are the purple nonsulfur bacteria that do both, photosynthesize and get their energy from organic compounds. Some symbiotic bacteria help us digest the food we consume. These beneficial gut flora provide us with essential nutrients like vitamin B1 & B6 we cannot make ourselves. There are over 800 known species living in humans but people do not have all. Different populations of people have different collectives of gut bacteria. Understanding what a specific group of bacteria do in the gut and how they work together to digest may affect how we get energy from our food and gain weight.
Agar, in agar plates used in culturing bacteria and other microorganisms, consists of a gelling agent, and is an unbranched polysaccharide obtained from the cell walls o…f some species of red algae, primarily from the genera Gelidium and Gracilaria, or seaweed. As very few bacteria are able to decompose the actual agar itself, nutrients such as glucose must be added to the agar mixture to allow bacterial growth. It is these various nutrients that the bacteria feed on to survive. The typical agar plate contains: # A carbon source such as glucose for bacterial growth # Water # Agar # Various salts needed for bacterial growth # A source of amino acids and nitrogen (e.g., beef, yeast extract) This particular mix is an undefined medium because the amino acid source contains a variety of compounds with the exact composition being unknown. In this case, most bacteria will be using all the above except 3. Agar for nutrition.
Most of the nutrients are absorbed in the small intestine and water, some vitamins and electrolytes (sodium, potassium ions) are absorbed in the large intestines.
In body,nutrients are absorbed in Small intestine by micro-villi present on the wall of it.
What are all over the outside of the small intestine to absorb nutrients and deliver them to cells of the body?
