Answer:
The structure of mitochondria contains the foldings in the inner side called "cristae" which increase the surface area of the mitochondria. The cristae are important to mitochondria as well as cell as cristae embody the ATP synthase enzymes which help in the formation of the ATP molecules.
Heart cells require more energy to pump the blood from the heart to the body so it needs a more mitochondrial number in the cells with more infoldings to synthesize more ATP.
Answer:
The correct answer is option d. "The various substituents on the tetrapyrrole ring alter the absorption properties of the pigments".
Explanation:
In chlorophyll and bacteriochlorophyll pigment molecules absorb light energy for photosynthesis at different spectrums. The means at which absorption spectrum is controlled is by the fact that the various substituents on the tetrapyrrole ring alter the absorption properties of the pigments. The tetrapyrrole ring has a a magnesium atom at its center, which in conjuction acts as an antenna for light's absorption.
