Their only exit is through the ATP synthesizing enzyme that is located in the confining membrane. As the hydrogen passes through the ATP synthesizing enzyme, energy from the enzyme is used to attach a third phosphate to ADP, converting it to ATP. Figure 5. A generalized view of an electron transport system.
Hair length is completely controlled by the length of the anagen phase of your hair follicle. How long this period lasts is generally determined mostly by genetics, but can also be affected by hormones, and even extreme stress.or the hair on your head, the average length of the anagen phase is about 2-7 years. For your arms, legs, eyebrows, etc., this phase usually lasts just 30-45 days.
Hair grows in a follicle, a bulb-like tube on your scalp. The average head has 100,000 to 150,000 follicles, each operating independently from the others. Hair in its basic, unpigmented state is white. It gets its color from melanin, a pigment that also determines skin color. Two types of melanin, eumelanin (dark brown or black) and phaeomelanin (reddish yellow), combine to make all the hair colors.
