QuestionAnswer
What deals with the structure and function of living things? life science
Living things are all made of what? matter
What makes up all matter? atoms
What makes up more than 70-75% of all cells volume and is essential for life? water
What type of compounds contain Carbon and Hydrogen and are usually associated with living things? organic compounds
Which molecules are the building blocks of structures in a cell? proteins
Which of the following list of element symbols are the most often found in living things? N,C,H,O,P,S,Ca,K
Which of these elements are not normally found in living things? Radon
What are examples of of carbohydrates? sugar, starch, cellulose
Which organic compound is great for storing coded information? nucleic acids
Which organic macro-molecule compound is best for forming boundaries? lipids
H2O is the symbol for what inorganic compound? water
What type of membrane is a cell membrane? semi-permeable
What do we call the normal rigid state of fullness in a cell or blood vessel? turgor
What do we call the diffusion of water? osmosis
What type of transport requires energy to move from areas of low concentration to areas of high concentration? active transport
What do we call the random movement of substances from an area of higher concentration to an area of lower concentration? diffusion
What type of transport is it when molecules are so large they must pass through a cell membrane using special proteins called transport protiens? facilitated diffusion
What type of active transport is it when a cell takes in substances by surrounding it with the cell membrane? endocytosis
What do we call it when substances cross the cell membrane. but does not use the cell's energy? passive transport
What type of active transport is it when a cell releases its contents from an area of low concentration to an area of high concentration? exocytosis
What represents the energy made in respiration? ATP
What is a series of chemical reactions that take place in a chloroplast of a cell to produce food? photosynthesis
Where in a cell does glycolysis occur? cytoplasm
In what part of a cell does aerobic cellular respiration take place? mitochondria
What does the part of cellular respiration that happens in the mitochondria require? oxygen
What does C6H12O6 stand for? Glucose
What chemical equation is C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP? aerobic cellular respiration
Water + Carbon Dioxide + Sunlight --> Glucose + Oxygen is the word equation for what process? photosynthesis
In what part of the cell does photosynthesis take place? chloroplast
What is another name for fermentation? anaerobic respiration
What do humans use to gain energy when oxygen levels are low? lactic acid fermentaion
In what organism or organisms does respiration occur? plant and animal
What is the word equation for aerobic cellular respiration? glucose + oxygen --> water + carbon dioxide + ATP
What are the two types of fermentation? alcohol and lactic acid
true of false: oxygen and sugar are used in a process that povides energy to cells; water and carbon dioxide are its waste products true
true or false: Water and sugar are used in the process that provides energy to cells; oxygen and carbon dioxide are its waste product false
The transfer of nitrogen from the atmosphere to plants and animals is which cycle? nitrogen cycle
Would osmosis occur across a permeable membrane that separates solutions of the same concentration? not likely
Would osmosis occur across a permeable membrane that separates solutions of different concentrations? yes
What are the types of active transport? endocytosis and exocytosis
Which way do molecules flow during active transport? low to high
Which way do molecules flow during passive transport? high to low
What are the types of passive transport? diffusion, osmosis and facilitated diffusion
When molecules are spread evenly it is called? equilibrium
Be able to identify illustrations of active transport, diffusion, osmosis and equilibrium
How are the photosynthesis and respiration related to the carbon cycle? photosynthesis uses the carbon in carbon dioxide to make glucose, while respiration breaks down glucose containing carbon and gives off carbon dioxide
