The correct answer is (B) False.
There is not as much energy used to add a phosphate group by means of phosphorolysis, as the energy required adding a phosphate using ATP.
What is Phosphorolysis?
- Glycogen phosphorolysis is a process that occurs at the start of glycogen breakdown. As a result, glucose can be produced from glycogen.
- Glycogen phosphorolylsis catalyzes glycogen phosphorolytic cleavage, resulting in glycogen-1-phosphate.
- However, when cleaving glucose from glycogen, a non-reducing terminal is eliminated.
- Furthermore, phosphoglucomutase can convert glucose-1-phosphate generated from glycogen into G6P, allowing it to go directly to glycolysis.
- It should be noted that going straight to glycolysis eliminates the need for ATP to convert glucose to G6P.
- If the glucose created by glycolysis is consumed, three ATPs are produced.
- Phosphorolysis requires less energy than ATP to add a phosphate group.

Answer:
The answer is insulin.
Explanation:
Pancreatic juice is an enzyme containing secretion produced by the pancreas into the small intestine. Enzymes in the pancreas help in digesting proteins, carbohydrates and fats. The constituent enzymes are as follows:
- Trypsinogen and Chymotrypsinogen: Precursors of the proteases, trypsin and chymotrypsin that digest proteins. They are released as precursors to protect the intestinal lining. Enterokinase, an enzyme secreted by small intestine's epithelial cells, activates these precursor.
- Lipase: Enzyme that digests lipids by hydrolysing triglycerides into 2-monoglyceride and two free fatty acids.
- Amylase that helps in digesting any left over carbohydrates and complex starch.
Insulin:
Insulin can never be part of pancreatic juice because it is a hormone, not an enzyme. Hormones are chemical messengers secreted only in blood. Insulin is a hormone secreted by the pancreas to lower blood glucose levels by binding to insulin receptors on cells and stimulating the intake of glucose through glucose transport channels (GLUTs) in the cell membrane.
Answer:
C
Explanation:
Prokaryotic cells doesn't have any nucleus, so the first one is incorrect. No cell can function without genetic information, so the last one is incorrect. Plasmids are present only in Eukaryotic cells, so the second one is incorrect. Which leaves the third one as correct.
