What is the "building block" of carbohydrates? |
Carbon |
|
|
What is an example of a carbohydrate (something found in food, but not a food)? |
Glucose, starch, cellulose, fructose-- any one of these would work, but stick with glucose just to be 100% sure. |
|
|
What is the use of carbohydrates? |
To provide the body with short bursts of energy. |
|
|
What foods contain a lot of carbohydrates? |
Candy. (Contains lots of monosaccharides or simple sugars) |
|
|
What is the "building block" of proteins? |
Amino acids |
|
|
What is the "building block" of nucleic acid? |
Nucleotides |

glycerol |
|
|
What is an example of a nucleic acid(something found in food, but not a food)? |

|
|
What is the use of proteins? |
Builds muscle, breaks down food, transports oxygen, etc. |
|
|

|
|
Compare an atom, an element and a compound. |
An atom is one unit of an element, an element is something made up of entirely one type of atom, and a compound is several elements bonded together. |
|
|
Ionic bonds vs Covalent bonds! Go! |
Ionic-- one element gives valence electrons to the other. Covalent-- both elements share valence electrons. |
|
|
What particles are responsible for forming chemical bonds? |
Electrons. |
|
|
What are the elements that enter a reaction called? What are the ones that exit a reaction called? |
Reactant and Product |
|
|
Compounds containing organic molecules are called... |
Organic compounds |
|
|
How many valence electrons does Carbon have? how many bonds can it form? |
4 and 4 |
|
|
Dehydration synthesis is= |
The process in which carbon is linked together by the removal of water. |
|
|
Hydrolysis is= |
The process of carbon bonds being dissolved by adding water. |
|
|
What 3 elements are found in carbohydrates? in what ratios? |
Carbon, hydrogen, and oxygen 1:2:1 |
|
|
What is the storage form of glucose in plants? Animals? |
Starch and glycogen |
|
|
MAin groups in protein? |
Amino group, carboxyl group and R group |
|
|
What determines the function of protein? |
The R group |
|
|
What structures compose a nucleotide? |
5-carbon sugar, phosphate group and nitrogenous base |
|
|
Chemical reaction for photosynthesis? |
6CO2 + 6H2O ------> C6H12O6 + 6O2 instigated by sunlight energy |
|
|
What are the reactants in photosynthesis? |
6CO2 + 6H2O (six carbon dioxide and six dihydrogen monoxide (water)) |
|
|
What are the products in photosynthesis? |
glucose and oxygen (1 and 6, respectively) |
|
|
What structure absorbs light in photosynthesis? In what colors? |
Chloroplasts contain the pigments chlorophyll A and B that absorb reddish purple and purple, and blue and reddish orange, respectively. Carotenoids absorb blue and green. |
|
|
What is the function of ATP and how does it work? |
ATP is used to provide energy to cells. Cells convert glucose into ATP when energy is needed, but they only convert as much as they need because ATP is unstable. |
|
|
Where does the light dependent reaction happen in photosynthesis? |
In the thylakoids. |
|
|
Where does the light independent reaction happen in photosynthesis? |
In the stroma. |
|
|
What happens to water during the light dependent reaction in photosynthesis? |
The water is broken up into one oxygen and two hydrogen atoms. |
