Unit 2 Flashcards
What is the main component of our cells and what percentage does it make up of our body?
Water and 60%.
What word describes water that is inside our cells and what is an example of such?
Intracellular fluid and cytosol.
What word describes water that is found outside of our cells and a example off such.
Extracellular fluid and interstitial fluid, plasma.
What is RBC?
Red blood cell.
What are the three types of solutions for RBC? Describe what it is and what it does to the RBC.
-Hypertonic, 90% water and 10% sugar. Because of high solute, water moves from outside of the cell and trys to dilute there sugar. Causing crenation of the cell.
-Isotonic solution, 98% water and 2% sugar. This is the perfect solution and causes RBC to be very happy.
-Hypotonic solution, 100% distilled water. This causes hemolyse in the cell because of too much water.
Is water polar or non polar?
Polar.
Because of waters polarity what does it cause to ionic compounds?
The dissolve of a ionic compound because ionic bonds are polar. Polar ❤️ polar.
What is an example of a non polar compound that water cannot breakdown?
Fat(triglycerol).
Does water have a low or high heat capacity? Why?
High heat capacity, because water absorbs and releases lots of great before it significantly changes(temp homeostasis).
Does water have high heat of vaporization?
Yes.
In what reaction is water a essential reactant? Example?
Hydrololysis reactions. Sucrose + H2O –> Glucose + Frutose is a example.
What type of fluid is a cushion for joints?
Synovial fluids.
Water tends to do what?
It tends to ionize (dissociate).
What are the qualities of water? Describe.
Cohesive, they are polar so each molecule sticks together.
Has high surface tension because of cohesiveness.
Adhesive, water likes to stick to other molecules which allow for water to transport up.
Transpiration.
