First, the bicarbonate ion is phosphorylated by ATP (step 1, see section 10.2), and thus is activated for decarboxylation, which generates free CO 2 (step 2). WebPantothenic acid (B5) and biotin (B7) are types of B vitamins. They are water-soluble, which means that the body can't store them. If the body can't use the entire vitamin, the extra amount leaves the body through the urine. The body keeps a small reserve of these vitamins. They have to be taken on a regular basis to maintain the reserve. css force no line break
