Explain chemiosmotic coupling.
The mechanism of coupling electron transport to ATP generation.
The energetically favorable transport of small molecules down a concentration gradient can be used to drive the synthesis of ATP. 
21. Genes and chromosomes 
Genes are traits that are which are inherited by certain factors; one gene copy (an allele) specifying a trait is inherited one from each parent
Chromosome- carriers of genes 
22. Roles of mRNA, tRNA, and rRNA 
mRNA carriers information from DNA to the ribosomes 
tRNA serves as adaptors between amino acids and mRNAs 
rRNA is a component of ribosomes 
Enzymes can be regulated from allosteric sites which can be positive= activator or negative=inhibitor. Small molecules bind outside catalytic site to change activity of enzyme. Phosphorylation also has enzymes can have a phosphate group covalently attached to serine, threonine or tyrosine amino acid. Negative charge changes the shape and activity and positive or negative regulation
