    e. Protein kinase C activity

    2) Touch receptors per unit area in mucosa are max. in
    a. uvula

    hi..well, even i thought of this answer, bcoz intracellular K concentration vil directly b affected by aldosterone which is a steroid, but insulin also helps in increasing cellular uptake of K, thus increasing its concentration in the cells..and insulin is a polypeptide..so, i m really not sure...correct me if i m wrong..thanx..
