Prokaryotic cells (bacteria) have several cell components that may or may not give it an edge when it comes to survival in a har

sh environment. Review the cell components of prokaryotic cells once again. Discuss the components of the cell that can help the cell survive and evolve to become stronger and resistant to death.

Answer and Explanation:

All the components a prokaryotic cell can have are:

- Plasma membrane

- Cell wall

- Capsule

- Cytoplasm

- Nucleoid (where DNA is, it is not an actual nucleus)

- Plasmid

- Ribosomes (for protein synthesis)

- Pillus or Pili

-Flagellum or flagella

-Fimbria or fimbriae

A typical prokaryotic cell have plasma membrane, cytoplasm, nucleoid (genetic material) and ribosomes. Some prokaryotic cells have also cell wall, capsule, plasmids, pili, fimbriae and flagella and these components can be used for the cell to survive to unfavourable conditions.

Cell wall mantains the shape of the cell, prevents dehydratation and gives extra protection. Capsule is useful for the cell to attach surfaces. Plasmid is a circular molecule of DNA which is able to replicate independently of the chromosome (in nucleoid) and it can be transfered through a pillus to another prokaryotic cell. Plasmid can contain a gene that confers bacteria an antibiotic resistance, so if the cell posses the plasmid, it is resistent to the antibiotic. Flagellum is used for locomotion (to move on in a medium) and fimbriae are used to attach to surfaces.

One role of the pancreas is to help regulate blood glucose levels. Two types of cells in the pancreas, beta and alpha, serve as
solniwko [45]

1. Regulation of glucose blood levels is an example of negative feedback mechanism.

Negative feedback mechanism is a control mechanism involved in homeostasis maintain, in this case maintenance of glucose blood levels in normal range.

Negative feedback mechanism contains sensory system that detects the changes, control system that responds to change and activates mechanisms of effector system that reverse the changes in order to restore conditions to their normal levels.

• Pancreatic cells-sensors

• Insulin-control system

• Body cells- effector cells

2. Blood glucose levels change throughout the day because of the food consumption, but in healthy individuals levels of glucose are successfully regulated via the mechanism of hormones such as insulin and glucagon in a process called glucose blood regulation.

This tight regulation of pancreatic hormones is referred to as glucose homeostasis. Insulin lowers blood sugar and glucagon raises it.

3. If the beta cells are destroyed by an autoimmune disease (immune system attacks its own cells), there would be no insulin release, and consequently, the glucose blood levels would be increased.

Diabetes type I is a metabolic disorder caused by the destruction of insulin-producing pancreatic beta cells.
