6 FAQs about [Important energy storage substances for bacteria]

How do bacteria store energy?

Energy metabolism in selected bacteria Bacterial metabolism includes intracellular catabolic and anabolic processes. Most bacteria use sugars as energy sources, release energy through aerobic oxidation or the anaerobic fermentation of sugars, and store energy in the form of ATP.

How do bacteria metabolize energy?

Abstract Bacteria power their energy metabolism using membrane-bound respiratory enzymes that capture chemical energy and transduce it by pumping protons or Na+ions across their cell membranes.

How do bacterial metabolites affect systemic energy expenditure?

Among the most important bacterial metabolites are short-chain fatty acids, which serve as a direct energy source for host cells, stimulate the production of gut hormones and act in the brain to regulate food intake. Other microbial metabolites affect systemic energy expenditure by influencing thermogenesis and adipose tissue browning.

What are examples of energy metabolism of bacteria?

At the end of the chapter some examples/case studies of energy metabolism of bacteria are provided and related to the medical interest in these bacteria. Bacteria can gain energy by a number of processes: aerobic respiration, anaerobic respiration, fermentation and photosynthesis.

Why do bacteria have a membrane transport system?

Bacteria have membrane transport systems for the uptake of sugars against steep concentration gradients energized by ATP, the proton motive force and the high energy glycolytic intermediate phosphoenolpyruvate (PEP).

How do bacteria use a variety of electron sources?

The capacity of bacteria to use a variety of electron sources is impressive. When organic matter provides the energy, succinate, NADH or succinate dehydrogenase enters the electron transport chain and acts similarly to Complex II in mitochondria (Unden and Bongaerts 1997).
