Answer:
Structure: unicellular organisms (single-celled), no nucleus or membrane-bound organelles, genetic material usually composed of a single circular bacterial chromosome coiled up in a region of the cytoplasm
Function: metabolic functions are carried out in the bacterial cytoplasm
Replication: generally asexual (binary fission)
Explanation:
Bacteria are prokaryotic organisms, i.e., unicellular organisms that do not have a cell nucleus nor any membrane-bound organelles
. Generally, the genetic material is composed of a single DNA circular molecule (bacterial chromosome), which is localized in a specific region of the cytoplasm (nucleoid region). Prokaryotic cells are usually smaller than eukaryotic cells (0.1 - 5 μm in size). In bacteria, metabolic functions (i.e., growth and reproduction) occur in the cytoplasm. The most important process of reproduction in bacteria is binary fission, a form of asexual reproduction where a single bacterial cell divides into two. Bacteria can also exchange genetic material by sexual reproduction mechanisms (i.e., conjugation, transformation and transduction). The main strategy to prevent outbreaks caused by bacteria is to know the conditions where they grow and reproduce. For example, <em>Salmonella</em> is a genus of infectious bacteria that may cause an outbreak. <em>Salmonella</em> infection may be prevented by eliminating conditions where they can multiply. Measures to prevent <em>Salmonella</em> outbreaks include cook food thoroughly (do not eat raw eggs or raw beef), refrigerate foods, wash hands, etc.
Answer: Pyruvate is reduced and NADH is oxidized.
Explanation:
Fermentation is a chemical process that involves the breakdown of carbohydrates anaerobically by the activities of microorganisms.
It is the process use in the production of foodstuffs, wine and beer. Fermentation start with enzymes activities, which breakdown sugars into lactate or two molecules of three carbon organic acid, pyruvic acid. Pyruvate is reduced to lactic acid or alcohol in the absence of oxygen and nicotinamide adenine dinuleotide+hydrogen(NADH) is oxidized . This process produces two ATP per glucose molecule.
The wastes would build up in your blood, and can cause serious damage. You can also have serious infections and pain if your kidney is not functioning properly.
