Water & pH Powerpoint
Cell Powerpoint
Learning Outcomes:
- describe the characteristics of water and its role in biological systems
- describe how the polarity of the water molecule results in hydrogen bonding
- differentiate among acids, bases, and buffers
- describe the importance of pH to biological systems in the human body
- describe the following cell structures and their functions:
- – cell membrane
- – cell wall
- – chloroplast
- – cytoskeleton
- – cytoplasm
- – Golgi bodies
- – lysosomes
- – mitochondria – including cristae and matrix
- – nucleus – including nuclear pore, nucleolus, chromatin, nuclear envelope, and chromosomes
- – ribosomes (polysomes)
- – smooth and rough endoplasmic reticulum
- – vacuoles
- – vesicles
- state the balanced chemical equation for cellular respiration
- describe how the following organelles function to compartmentalize the cell and move materials through it:
- – rough and smooth endoplasmic reticulum
- – vesicles
- – Golgi bodies
- – cell membrane
- identify cell structures depicted in diagrams and electron micrographs
WRITTEN QUESTIONS (these will appear on your test)
- Draw two water molecules. Label hydrogen bonding, covalent bonding and partial charges.
- Describe how the polarity of water results in hydrogen bonding.
- Describe one property of water and explain it's role in biological systems.
- Use an ANALOGY to describe how the following organelles function to compartmentalize the cell and move materials through it:
- – rough and smooth endoplasmic reticulum
- – vesicles
- – Golgi bodies
- – cell membrane
- Using the equation below, explain what happens to an alkaline solution (basic) when you blow into it with a straw. Why does this change in pH occur more quickly if you exercise before blowing into the alkaline solution?
There will also be approximately 20-30 multiple choice questions on the test.
