Provided that there's no diagram, most molecules have particular areas on the molecules, called the "active area" that act as a lock to a particular substrate's molecular structure, providing the key.
An enzyme's active area is only able to be "unlocked" by a certain substrate's "key".
The baby is considered as extremely preterm infant.
The babies that are born alive before the completion of a period of 37 weeks of pregnancy are the preterm babies. There are three categories into which preterm born babies are distinguished: moderate to late preterm for 32-37 weeks, very preterm for 28-32 weeks and extremely preterm for less than 28 weeks.
Premature births are one of the major causes of death of children under the age of 5 years. The babies that survive may have problems and may be visual or hearing impaired, may have learning disabilities etc.
The correct answer is: E) cleavage furrow formation and cytokinesis
Cytochalasin B (cytos-cell and chalasis-relaxation) is a molecule which inhibit network formation by actin filaments by blocking monomer addition. As a result, itshortens actin filaments. This molecule is involved in cytoplasmic division where it blocks the formation of contractile microfilaments. One of the microfilament’s function includes cytokinesis and formation of cleavage furrow so these functions are affected by cytochalasin B.
