A nucleotide-sugar coenzyme involved in carbohydrate metabolism (UDP-glucose) is formed when UTP reacts with a glucose molecule. More UTP is made available for additional reactions by the transfer of a phosphate group from:.
a. ATP.
b. UDP.
c. ADP.
d. UTP.
e. Another carbohydrate.

b. UDP

Explanation:

Uridine diphosphate glucose (UDP) is a nucleotide sugar involved in galactose metabolism. In this reaction, the galactose 1-phosphate uridylyltransferase (GALT) enzyme transfers a phosphate group from UDP-glucose to galactose 1-phosphate in order to convert galactose into glucose

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
