5 Multiple choice questions
- Heart and lungs
- synthesis reactions: bonds are formed to join two or more atoms to make a new compound
(ex: proteins are sythesized by the bonding of many amino acids)
decomposition reactions: bonds are broken and a large molecule is changed to two or more smaller ones
(ex: digestion of starch into many smaller glucose molecules)
- process of cell division that results in the formation of gametes which are egg and sperm cells.
(used for creating human life)
- name for energy production within cells and involves the respiratory gases: oxygen and carbon dioxide
(ex: glucose and oxygen combine to make carbon dioxide, water, ATP and heat)
- covalent bond formed between two atoms of sulfur
(ex: strand of hair maintains its shape)
5 True/False questions
What are the cell organelles and what do they do? → ER or endoplasmic reticulum- are tubules that transport materials necessary for cell function within the cell.
Ribosomes- are very small structures made of protein and ribosomal RNA and are found on the surface of rough ER.
Proteasome- is a barrel shaped organelle made of enzymes that cut protein molecules apart.
Golgi apparatus- are flat, membranous sacs where carbohydrates are synthesized and are packed with other materials for cellular secretion.
Mitochondria- are oval organelles bound by a double membrane where cell respiration takes place and site of ATP production.
Lysosomes- are single membrane structures that contain digestive enzymes and eat dead cells and bacteria .
Centrioles- are a pair of rod shaped structures outside the nucleus that spindle fibers during cell division.
Cilia and Flagella- are thread-like projections through the cell membrane that can sweep materials across cell surface and flagellum provide mobility of the cell.
Microvilli- are folds of the cell membrane that increase surface area of membrane when needed. They are good for absorption of nutrients as well.
Cytoskeleton- are the framework and support of the cell. Made of microfiliaments.

What is mitosis? → Cell division involving one cell with the diploid number of chromosomes dividing into two identical cells.
(used for repair of tissues and growth of the organism)
What is a buffer and what does it do? → A buffer system is a chemical or pair of chemicals that minimizes changes in pH by reacting with strong acids or strong bases
(ex: buffer bonds to H+ ions when body fluid is becoming too acidic or release H+ ions when fluid becomes too alkaline)
