Question

In: Biology

identify: the type of metabolism, the fuel source and final electron acceptor, and the steps of respiration needed to generate ATP.

Name That Metabolism!

For each of the following descriptions, please identify: the type of metabolism, the fuel source and final electron acceptor, and the steps of respiration needed to generate ATP.

Case 4: Methanobrevibacter smithii is a type of bacteria that lives in the guts of cows and other organisms. These bacteria use the hydrogen gas and carbon dioxide produced by gut microbes during fermentation and produce methane gas (CH4).

Case 5: Paracoccus denitrificans is an extremophile which uses methane and nitrates (NO3) and produces carbon dioxide and nitrites (NO2).

Solutions

Expert Solution

Case 5: Methanobrevibacter smithii is methanogens, These bacteria use the hydrogen gas and carbon dioxide and produce methane gas (CH4).

Methanogenesis is the process of generation of methane by methanogens. so,  Methanobrevibacter smithii use Methanogenesis pathway to produce methane gas. The terminal electron acceptor in methanogenesis is carbon.

CO2 + 4 H2 → CH4 + 2 H2O

steps of methanogenesis: Check attached figure

Case 6: Paracoccus denitrificans

denitrification. : reduction of nitrates or nitrites by bacteria

Denitrification is the utilization of nitrate (NO3−) as the terminal electron acceptor.

steps : Check attached figure

Thank You!

What is not true in the description of chloroplast? Chloroplasts generate all of the ATP needed to drive cellular processes in plant cells. Plants use activated carriers to synthesize sugars and other food molecules, Chloroplasts can capture light energy and use that to produce ATP and NADPH. Chloroplasts convert sunlight energy to metabolic fuels that are then used by plant mitochondria to generate large amounts of ATP. The high energy electrons donated to the photosynthetic electron-transport chain come from the...
