13. Chemical Composition Of The Cell. Basic Chemcial Compounds Flashcards
What are the essential elements of the cell?
The essential elements are macro elements which is up to 99% of the cell mass. Macro elements are carbon, nitrogen, oxygen hydrogen. It is also contained of micro elements such as copper, zinc and magnesium. Lastly is has also ultra trace elements such as mercury, silver, uranium and radium.
Does it have inorganic and organic molecules?
It also has inorganic compounds such as free ions. They are bound with organic compounds such as carbohydrates, protein, lipids, nucleic acid and other organic substances.
How much of the cell is water? How much of its is exogenous and what does exogenous mean? How much of the water is endogenous and what does it mean?
Up to 80% of the cell is water. 2/3 of the cells water is exogenous meaning water that is brought in from outside the cell. 1/3 of cells water is endogenous which means the water that is produced within the cell.
Is water essential for all life to exist? How much of the molecules inside living cells are water molecules? How much of the total wet-weight of the cell is water? What matrix is water considered to be? How does it help with nutrients? What does it help the body with? How does the water pass through the membrane? What is the specialised channel called?
Water is essential for all life to exist. 99% of the molecules inside living cells are water molecules. It is up to 80% of the total wet-wet-weight of the cell. It is considered to be the matrix of life. Water is a solvent for nutrients. To maintain a constant Temperature and eliminate waste from the cell. Water passes through special channels in the cell membrane. They are called aquaporins.
What are carbohydrates divided into depending on their carbon atoms? What is a simple sugar? What are monosaccharides? What is the most common monosaccharide? What is a double sugar? How is the molecular weight? What are they soluble in? How is the taste? A common double sugar is? What is a complex sugar? How is the molecular weight? Is it soluble in water? How is the taste of complex sugars? What are carbohydrates for us?
They are divided into monosaccharide, disaccharide, oligosaccharide and polysaccharide depending on their carbon atoms.
Monosaccharides are simple sugars. Monosaccharides are either pentose, ribose or hexose. The most common monosaccharide is glucose. Disaccharides and monosaccharides are double sugars. They have low molecular weight. They are soluble in water. It’s taste is sweet. A common double sugar is sucrose. Polysaccharides are complex sugars. It’s molecular weight is high. It is insoluble in water. It is tasteless. Carbohydrates are the main source of our energy.
