Answer:
Answered below
Explanation:
Whoosh is an inhibitor of the f1fo ATP synthase. ATP synthase is an enzyme that catalyses the synthesis of ATP in the mitochondria through the process of oxidative phosphorylation, by using energy from the transmembrane electrochemical proton gradient along the respiratory chain.
ATP synthase is made up of two main subunits called the F0 and F1. These subunits allow for ATP production through their rotational mechanisms.
Various synthetic and natural inhibitors of ATP synthase have been used to study the structure and mechanism of ATP synthase. These inhibitors cause the decrease in the NAD/NADH ratio. They include; polypeptides, organotin compounds, cationic inhibitors, amino acid modifiers, oligomycin and peptide inhibitors.
The disk diffusion test is used to compare the effectiveness of antibiotics. The incubated plate (results) will show bacteria growth except where antibiotic has effects. The more effective the drug, the inhibition zone will be greater. So the most effective antibiotic is the one that has the largest inhibition zone around the test site.
Answer:
During any pandemic, government can make people aware about that pandemic and can provide the necessary things like shelter, food etc. to poor people. Government can also help people by money.
Answer:
The correct option is A. Steroid hormones exert their action by entering the nucleus of a cell and initiating or altering the expression of a gene.
Explanation:
Steroid hormones are derived from cholesterol and regulate multiple biological processes. All steroid hormones exert their action by crossing the plasma membrane and by binding with their respective intracellular receptors. They stimulate cell growth in a very different way, their lipophilic nature gives them the ability to cross lipid barriers, so, without the need for extracellular signals, these hormones can easily enter the cell, cross the cytoplasm and reach the nucleus. There they bind to specific receptors that are associated with DNA promoter regions, modifying their structure and promoting the expression of the genes under their control.
