What determines the shape of an enzyme? How does an enzyme affect an activation energy barrier? Why do enzymes only work on their specific substrates? Explain the role of enzymes in living cells. How does an enzyme's active site relate to its substrate?
Explain the role of enzymes in living cells. Explain why nearly all cells make some proteins. How would you explain the way in which one hormone interacts with another and its effect on the cells? What process results in the formation of sex cells?
This article aims to describe the role of sex hormones in sex- and gender-related fatality of COVID-19. We discuss the possibility that potential sex-specific mechanisms modulating the course of the disease include both the androgen- and the estrogen-response cascade. Sex hormones regulate the ...

(OAA). Previous studies have indicated that PEPCK plays an important role in the TCA cycle and glycolysis and affects the sugar contents of plant organs76,77,78. PEPCK controls the first step of gluconeogenesis, where glucose is synthesized from malic acid and OAA or noncarbohydrate carbon ...
Describe the primary structures in bacteria cells and explain the roles of each one. Provide an overview of the cell cycle and describe why and how it is regulated. Please explain the cell biological process in simple terms. Explain th...
Phytoestrogens mimic the protective effect of oestradiol using the same signalling pathway. The critical importance of up-regulating antioxidant genes, by hormonal and dietary manipulations, to increase longevity is discussed. 展开 关键词: gender aging estrogens phytoestrogens antioxidant enzymes free ...
and food constantly to the distal gastrointestinal tract push process. 3. chemical digestion: through a variety of digestive enzymes in the digestive fluid containing the role of macromolecules in food (mainly sugar, protein and fat) broken down into small molecules has the advantages of simple str...
Working of Lac operon This concept is proposed by Jacob and monad. Ecoli cells require 3 enzymes for lactose metabolism. These enzymes transport and breakdown lactose into galactose and glucose for energy release. These three enzymes are: (B-gl
