Answer:

E1: Pyruvate dehydrogenase, TPP, oxidative decarboxylation reaction

E2: Dihydrolipoyl transacetylase, Lipoamide and Co-enzyme A, transacetylation reaction.

E3: Dihydrolipoyl dehydrogenase, FAD and NAD+, oxidation reaction

Explanation:

Pyruvate dehydrogenase is a multi-enzyme complex with 5 co-enzymes and 3 apo-enzymes:

Pyruvate dehydrogenase (E1) , which uses thiamine pyrophosphate (TPP) as as co-enzymes to catalyze oxidative decarboxylation of pyruvate to hydroxyethyl-TPP.

Dihydrolipoyl transacetylase (E2): which uses lipoamide and coenzyme A as co-enzymes to catalyse the transacetylation from TPP to Lipoamide to form acetyl lipoamide.

Dihydrolipoyl dehydrogenase (E3)​​ which uses FAD and NAD+ as co-enzymes to catalyze the oxidation of lipoamide

Describe three clean coal technologies and how they can mitigate the environmental impacts of coal. Explain how they work and pr
Andrej [43]

Clean coal technology refers to a gathering of technologies being created in order to reduce the environmental influence of coal energy production and to mitigate global climate change. There are three distinct technological procedures accessible for the aim of capturing carbon as demanded by the clean coal concept:  

1. Pre-combustion capture: This includes gasification of a feedstock like coal to generate gas that may be shifted to develop a mixture of carbon dioxide and hydrogen gas, from which the carbon dioxide can be effectively separated and captured, transported, and eventually sequestered.  

2. Post-combustion capture: This is the capturing of carbon dioxide from the exhaust gases of combustion methods.  

3. Oxy-fuel combustion: The fossil fuels like coal are combusted in a mixture of oxygen and recirculated flue gas, rather than in air that hugely withdraws nitrogen from the flue gas allowing capturing of low-cost and efficient carbon dioxide.  

An initial example of a coal-based plant utilizing carbon capturing technology is a Swedish company Vattenfall's Schwarze Pumpe power station situated in Germany.

Which of the following is the largest particle in soil? A-clay B-sand C-silt D-humus
Akimi4 [234]

Well the soil classification is usually done on the basis of particle sizes and composition of soil.

<span>Clay </span>usually consists of particles less than 0.075 mm in size. It is a sticky soil and shows great changes in volume with variation in its water contact. It also shows considerable strength when air dried.

<span>Silt </span>has larger particles than clay and are mainly inorganic in nature. The particle size is less than 0.075mm and exhibits slightly plastic or non plastic behaviour.

Humus is soil consisting of dead and decaying organic matter. It is mainly organic in content but some inorganic particles may be mixed in it. The top soil in a tropical forest may be considered as humus.
