1 In a solution of potassium hydrogen iodate [KH(IO 3) 2 ] at 0.02 M the activity is 40% lower than the calculated hydrogen ion concentration, resulting in a much higher pH than expected.
This type of multicellular exocrine gland has a branched rounded secretory part attached to a single unbranched duct and is found mainly in sebaceous glands. simple branched acinar gland. simple tubular exocrine glands have. a straight tubular secretory portion attached to a single unbranched duct.his type of multicellular exocrine gland has a branched rounded secretory part attached to a single unbranched duct and is found mainly in sebaceous glands. simple branched acinar gland. simple tubular exocrine glands have. a straight tubular secretory portion attached to a single unbranched duct.
Exocrine glands are classified according to whether the duct system is unbranched (simple) or branched (compound), and according to the distribution of secretory versus ductile epithelium. If the duct and secretory portions are of uniform diameter, the gland is tubular.If the secretory cells form a dilated sac at the end of the duct, it is acinar, and if the secretory cells extend uniformly from the duct then form a sac, it is called tubuloacinar.f the duct and secretory portions are of uniform diameter, the gland is tubular.
