Equilibrium’ In Human Physiology - Medical Science Assignment Help

Assignment Task

1. Julie is a 14-year-old girl who wants to help people get better, in other words she wants to be a nurse when she grows up. Your clever, young patient is curious about cells and how the body works at the microscopic level, she has heard cells are the basic unit of life and understands that means cells are self-sustaining entities that use nutrients to create their own energy, can build proteins on demand, produce and discard their own waste products and can even replicate themselves.

Help Julie understand more about cells by answering the following questions (a-i).

1. Cells which are continually engaged in making high amounts of proteins will have an abundance of which small intracellular organelle? Very briefly outline the role this structure has in protein synthesis.
2. In relation to the plasma membrane, what is meant by the term ‘selectively permeable’? Describe the plasma membrane in terms of why some solutes can pass freely from one side to the other while other solutes cannot pass through the membrane without assistance. Identify two different types of proteins embedded in the plasma membrane which assist solutes to cross the membrane down their concentration gradient.
3. Explain primary active transport in your own words. Include information about the mechanism of transport across the cell membrane, the concentration gradient of the solute/s involved and whether or not direct energy is used during this type of transportation in a hospital setting it is common practice to place patients on IV fluids, such as a 0.9% saline solution or 5% glucose solution to restore or maintain the balance of vital solutes and water in the body. The concentration of these solutions is isotonic to the body’s physiological needs.
4. Why would you never administer a 9% saline solution to a patient? Use the terms associated with tonicity and apply your understanding of osmosis to help explain the effect on red blood cells.

MUTLIPLE CHOICE AND TRUE FALSE QUESTIONS:

1) To help make it clear to Julie the importance of the nucleus within a cell, choose the statement below which best explains the link between DNA (genetic code) stored in the nucleus and proteins produced in the cytoplasm.

a. The genetic code consists of amino acids joined together in a specific sequence which is copied and used to create a protein in the cytoplasm

b. DNA is copied in a process called translation and then transcribed into a protein using ribosomes in the cytoplasm

c. The genetic code holds the sequences of bases which is transcribed in the nucleus and codes for the correct order of amino acids to make a functional protein in the cytoplasm

d. The nucleus stores DNA in small sections of DNA called genes, genes are transferred to the cytoplasm and used as a template to form multiple proteins whenever required

2) Molecules too large to enter a cell via protein transporters can be brought into the cell via

a. Facilitated diffusion

b. Exocytosis

c. Endocytosis

d. Membrane protein pumps

3) The term ‘equilibrium’ in human physiology relates to

a. an even number of solutes either side of the cell membrane

b. an even volume of water either side of the cell membrane

c. an even ratio of solute to solvent either side of the cell membrane

d. All the above

4) Indicate whether the statement below is true or false:

Cells which have high energy demands will have an abundance of mitochondria in their cytoplasm.
