<span>Endospore is a protective structure that can
able to survive for long periods of time in soil and water in which they commonly
found. They are tough, dormant and non-reproductive structure which can
withstand heat, dryness, and toxic chemicals that would kill most other
bacteria produced by a small number of bacteria like the bacterium Bacillus
thuringiensis from the Firmicute family. To ensure the survival of a bacterium
through periods of environmental stress is the primary function of most
endospores. They are also resilient to gamma and ultraviolet radiation, chemical
disinfectants, desiccation, starvation, lysozyme and temperature and can survive any environmental assaults.</span>
In the animals control and co-ordination is done by the nervous system and endocrine system whereas in animals nervous system is adequately developed and consists of brain, spinal cord and nerves; in animals hormones are secreted by endocrine glands.
Phosphorylase kinase is a type of regulatory protein kinase which helps in the process of glycogen breakdown.
It sends signals and the process of phosphorylating occurs which then helps in the activation of glycogen phosphorylase and subsequent breakdown of glycogen in the body. This makes phosphorylase kinase the right option.
