Answer:

The correct answer would be white blood cells.

White blood cells (WBC) or leukocytes are the primary cells of the immune system.

These cells protect our body from a foreign invader or infectious agent.

On the basis of lineage, these cells are mainly of two types:

  • Myeloid cells: monocytes, neutrophils, eosinophils, and basophils  
  • Lymphoid cells: B cells, T cells, and natural killer cells.

Once an infectious agent enters our body, the immune cells get activated and fight back the infectious agent

In what ways do cells use energy

Image result for In what ways do cells use energy

Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adenine dinucleotide (NADH), which can be used throughout the cell to power metabolism and construct new cellular components.

Pepsi [2]

Answer: D) alpha: catabolism

Explanation:

Glycogen is the storage form of carbohydrates in animals. The major sites of storage are liver and muscle.

Glucagon is a polypeptide hormone, it is secreted by the alpha cells of the pancreas. Low blood glucose causes glucagon secretion. When blood glucose level falls, liver glycogen is broken and help to maintain blood glucose level.

Glucagon stimulates the enzyme glycogen phospholylase which breaks down glycogen into glucose units.
