Cytochromes:- They are iron containing hemoproteins that serve many cellular functions including energy production, steroid biosynthesis, and degradation of toxins.
Cytochromes occur in all organisms except a few obligate anaerobes. They are structurally similar among organisms. These are proteins to which one to two tetrapyrrole rings are bound. These tetrapyrroles are very similar to the chromophores of chlorophylls in plants. However, chlorophylls(in plants) contain Mg++ as the central atom in the tetrapyrrole, whereas the cytochromes(in aerobic animals) have an iron atom (Figure).
Answers and Explanation:
Find enclosed the Punnet square.
T= dominant allele
t= recessive allele
Tt= heterozygous genotype
TT and tt= homozygous genotype
- The male pea plant's genotype is Tt (heterozygous)
- The female pea plant's genotype is Tt (heterozygous)
- Male gametes: T and t
- Female gametes: T and t
- The expected genotypic ratio of the offpring will be:
TT: Tt: tt ⇒ 1: 2: 1
1/4 of the offpring will be TT genotype (dominant homozygous), 1/2 of the offpring will be Tt (heterozygous) genotype and 1/4 of the offpring will be tt genotype (recessive homozygous).
- The expected phenotypic ratio of the offpring will be:
tall : short ⇒ 3 : 1
3/4 of the offpring will be tall (TT and Tt) and the restant 1/4 will be short (tt).
The right option is; Absorption
Transport of a substance from the lumen (cavity) of an organ into one side of a cell and out the other side of the cell into the ecf is called absorption.
Absorption is the process of assimilating substances into cells or through the tissues and organs. Absorption is done through osmosis or diffusion. Absorption of substances takes place within the body such as the absorption of drugs into the bloodstream, and the absorption of nutrients by the digestive system.
