Answer:
B) rough ER → Golgi complex → Golgi vesicle → extracellular fluid
Explanation:
- Insulin is synhtesized by beta cells of pancereas (preproinsulin).
- Insulin enters the rough endoplasmic reticulumn in its inactive form (proinsulin).
- The rough endoplasmic reticulumn converts it to active form (insulin).
- The rough endoplasmic reticulumn transfer the insulin to glogi comlpex
- The Golgi complex secrete it in golgi vesicles to cytoplasm.
- On the stimulation of beta cells insulin is secreted to extracellular fluid..
In the citric acid cycle (also
known as Kreb’s Cycle), the enzyme that catalyzes oxidative decarboxylation reactions
is α-Ketoglutarate dehydrogenase. The oxidative decarboxylation reaction is the
irreversible stage of the citric acid cycle; it generates NADH (equivalent of
2.5 ATP), and regenerates the 4C chain (CoA is excluded).
Answer:
The original water sample contains 830,000 cells per milliliter.
Explanation:
A sample of well water is tested for its bacterial content in a plate count assay. A one-milliliter sample of the water is diluted in a 1:10 dilution series. One milliliter of the fourth dilution tube is plated in a pour plate. After incubation, the plate has 83 colonies, indicating that the original water sample contained 830,000 cells per milliliter.
