Answer:
 α‑ketoglutarate dehydrogenase 
Explanation:
This is an enzyme complex ,which is analogous to pyruvate dehydrogenase. . Its catalytic activity is inhibited by it products succinyl Co A,it is also refers to as oxoglutarate dehydrogenase complex.(OGDC).
 This enzyme complex  is similar to pyruvate dehydrogenase in  having  the same subunit structure, and using  the same type of co-enzyme.    
 
        
             
        
        
        
Answer:
Extrinsic regulatory mechanisms are external and depend on the firing of some factor outside the population itself. Among them are interspecific competition, food and space restrictions, very strong climatic variations, weathering and inharmonious relationships with other populations (parasitism and predatism). 
Good examples of interspecific competition appear when rabbits, caves, rats compete for the same plant, or different fish and birds, such as the heron, vie for the same species of smaller fish. This is because these different species keep their populations in the same ecological niche. Competition is often so strong that some species eventually, as one example of an extrinsic homeostatic mechanism overriding an intrinsic homeostatic process is their disappearance or migration to other regions. 
 In this competition, the presence of adaptations among individuals in the population that promote better food search, speed, vision, and others can make the difference between elimination and survival.

Explanation:
Rhizopus is a genus of common fungi that develops on plants and specialized parasites on animals, it is fairly common in all kinds of foods like mature fruits, jellies, syrups, bread, peanuts, etc. They develop hyphae called rhizoids on this food and can be visible.
