Answer:
The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature to increase the surface area for reactions (electrochemical gradient) by accommodating protons pumped into it by the proton motive force(PMF) from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.
Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.
Explanation:
Answer: As estrogen and testosterone levels fall in later life, the frequency of intercourse decline or decrease and the frequency of sexual fantasies also decrease or decline.
The sex hormones have an impact and regulate or direct the male and female physical development of the sexual characteristics. The hormones testosterone and estrogen are present both in males and females but the males have higher testosterone levels and females have higher estrogen levels.
In humans the hormones impact the sexual behavior at a lower level once the sufficient level of hormones is present. In the later part of life, with the decline in level of the sex hormones the frequency of intercourse as well as the sexual fantasies decline.
