BRM 6 Science Respiration & Photosynthesis (first page in packet) {STUDY PACKET!}
WHat does the following represent?: C6H2O6
glucose
Where does the second stage of respiration take place?
in the mitochondria where small molecules are broken down into even smaller molecule. the chemical reactions require oxygen and a lot of energy is released in the "power house" of the cell.
Where does lactic acid take place?
in your body
What does your body do after you eat a meal?
it converts some of the food into glucose, a type of sugar
In which organelles does cellular respiration take place?
mitochondria
What happens during photosynthesis?
plants capture the energy from sunlight and "save" it in the form of carbohydrates
During photosynthesis, what are carbon dioxide and water used to produce?
sugars and oxygen
Name two forms of carbohydrates
sugars and starches
What is the relationship between the equation for respiration and photosynthesis?
they are opposite processes
Where do plants get their sugar?
they make their own through photosynthesis
Some organisms, such as single cell organisms, are able to obtain energy from food without using oxygen. Where do they obtain their energy?
through fermentation
How does your body get rid of the carbon dioxide produced by cellular respiration?
through your lungs
how does your body get rid of the carbon dioxide produced by cellular respiration?
through your lungs
Name a single-cell organism.
yeast
What do the respiratory system and cellular respiration have in common?
Oxygen plays a key role in both.
What two processes work together to maintain a fairly constant level of oxygen and carbon dioxide in the Earth's atmosphere?
Photosynthesis and Respiration
What's one major reason human cells have evolved to depend on aerobi, and not anaerobic, respiration?
aerobic respiration produces more energy than anaerobic respiration
What's one major reason human cells have evolved to depend on aerobic, and not anaerobic, respiration?
aerobic respiration produces more energy than anaerobic respiration
What does the following represent: 6O2
air
Where does the oxygen used in respiration come from?
air and water surrounding the organism
Name two types of fermentation:
alcoholic (yeast) and lactic acid
What kind of fermentation is useful to bakers?
alcoholic fermentation
How are plants and animals related in respiration and photosynthesis?
animals use oxygen produced during photosynthesis and plants use the carbon dioxide produced during respiration
Do plant cells or animal cells respire?
both, all living things carry out respiration continuously
In fermentation, what do cells use instead of oxygen to break down glucose?
carbon dioxide
What is a source of bubbles in beer?
carbon dioxide
in fermentation, what do cells use instead of oxygen to break down glucose?
carbon dioxide
Is CO2 carbon DIoxide or carbon MONoxide?
carbon dioxide (2=di)
During respiration, what are sugar glucose and oxygen used to produce?
carbon dioxide and water
What are the chemical products of cellular respiration?
carbon dioxide, water, and ATP
What happens during repiration?
cells break down simple food molecules, such as sugar and release the energy they contain
How do we get the glucose we need to power our cells?
eating
how do we get the glucose we need to power our cells?
eating
Which cells in your body undergo cellular respiration?
every cell in your body
Where doe cells or animals and other organisms get their glucose?
from the food they consume
What causes lactic acid?
lack of oxygen for the muscles. your muscle cells use up the oxygen faster than it could be replaced causing fermentation
in which organelles does cellular respiration take place?
mitochondria
What do the respiratory system and cellular respiration have in common?
oxygen plays a key role in both
Does fermentation or respiration release more energy?
respiration
Which produce more energy, aerobic respiration or fermentation?
respiration
What are the two things we need for respiration?
sugar (food) and oygen (breathing)
What are the raw materials for respiration?
sugar and oxygen
What causes bread to rise?
the carbon dioxide produced by yeast creates air pockets in dough
What is respiration?
the process by which cells obtain energy from glucose.
What is fermentation?
an energy-releasing process that does not require oxygen
When you breathe in, you take in oxygen, when you breathe out you release what?
carbon dioxide
What is the term for the respiration process that takes place inside the cells?
cellular respiration, not to be confused with "breathing" which is moving air in and out of your lungs
which cells in your body undergo cellular respiration?
every cell in your body
ATP is to your cells as _ is to a car
gasoline
ATP is to your cells as ____ is to a car.
gasoline
which produces more energy, aerobic respiration or fermentation?
respiration
Respiration is a two-stage process. What is the first stage?
It takes place in the cytoplasm of the organism's cells. Molecules of glucose are broken down into smaller molecules (oxygen is not involved and little energy is released)
What happens when cells need energy?
they withdraw it by breaking down the carbohydrates in the process of respiration
What are two other products of respiration (in addition to energy)?
water and carbon dioxide which diffuse out of the cell
What do you experience when lactic acid builds up in your body.
your muscles feel weak and sore and could have muscle cramps
