Question | Answer |
---|---|
Can animals survive without plants? | No |
What is the formula for photosynthesis? | 6CO2 + 6H2O + energy -> C6H12O6 + 6O2 |
What is the formula for respiration? | C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy (ATP) |
____ make their own food. | Autotrophs |
___ obtain energy by consuming other organisms. | Heterotrophs |
Give an example of a heterotroph. | Animals |
Give an example of an autotrophs. | green plants |
Living things need ____ to survive and function. | Energy |
Where does all the energy come from? | The Sun |
During ____ the energy from the Sun is transformed into a form of stored energy called ____. | Photosynthesis, glucose |
What has more energy? Glucose or ATP? | Glucose |
Because glucose is such a large amount of energy it has to be transformed into ____ so that the cell can use it. | ATP |
What process turns glucose into ATP? | Cellular respiration |
What does ATP stand for? | Adenosine triphosphate |
What is the universal energy molecule? | ATP |
Name the three parts of ATP. | Ribose (sugar) Adenine (base) 3 phosphate groups. |
What is the high-energy bond? | The bonds between the phosphate groups. |
When the energy is used the ATP is converted to what? | ADP (Adenosine DIphosphate) |
What happens when a phosphate group is removed? | Energy is released. |
Where do cells store extra energy until it is needed by the cell? | In the last phosphate bond of ATP. |
What traps light energy? | Chlorophyll |
What is absorbed from the roots of a plant? | Water |
What is glucose converted into after photosynthesis? | Starch which is stored food in other parts of the plant. |
What enters through the stomata of the leaflets? | Carbon dioxide ( CO2) |
What is photosynthesis? | In the presence of light, plants transform water and carbon dioxide into glucose and oxygen. |
What is the openings of a plant's leaves that allow carbon dioxide to come in and oxygen to go out? | Stomata |
What controls the opening and closing of the stomata? | Guard cells |
What is organelles found inside photosynthesis eukaryotic cells. | Chloroplast |
Pigment in plant cells that traps light | Chlorophyll |
Sacs that contain chlorophyll | Thylakoids |
Stack of thylakoid | Granum |
Area in chloroplast and outside of thylakoids | Stroma |
Plants absorb certain wavelengths of light. What are the two main ones. | Blue and red |
Molecules that absorb light | Pigments |
How do plants trap energy | By absorbing light |
What is the main pigment in plants | Chlorophyll |
What are two ways or cells use ATP | To break down molecules and active transport |
How many ATP are formed by the end of a aerobic cellular respiration | 36 |
Where does glycolysis occur and name the products | I cause this occurs in the cytoplasm and it produces 2 ATP and 2 pyruvate |
Where does the Krebâs cycle occur and name the products | It occurs in the minor contra and produces CO2 and 2 ATP |
Where does the electron transport chain occur and name the products | It occurs in the mitochondria and it produces H2O and 32 ATP |
What are the two types of fermentation | Alcoholic and lactic acid |
If oxygen is not present what are the two steps for anaerobic respiration | Glycolysis and fermentation |
What types of cells reform each type of fermentation | Alcoholic is performed by bacteria while lactic acid is performed by muscle cells |
Why are you are lungs important for cellular respiration | They help you get oxygen |
What type of organism does photosynthesis occur in | Autotrophs |
In what type of organism does respiration occur | Autotrophs and heterotrophs |
What happens in photosynthesis | Water and carbon and light go into a plant cell and produces glucose and oxygen |
What happens in cellular respiration |
