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.
Modes of Secretion. Secretory cells of exocrine glands release their products into ducts in three different ways. The mode of secretion can be classified as merocrine, apocrine, or holocrine. Cells that secrete products via the merocrine method form membrane-bound secretory vesicles internal to the cell.odes of Secretion.
