Glucose
What substance is needed to carry out respiration?
Oxygen
What are all the products of cellular respiration?
Carbon Dioxide, water, and energy
Plants do not use the process of cellular respiration.
False
What many stages are their in cellular respiration?
2
Where does the first stage of cellular respiration take place?
cytoplasm
Where does the second stage of cellular respiration take place?
mitochondria
Fermentation is an adaption to an environment that..
Has a small amount of no oxygen
Alcohilic fermentation is important to bread rising
True
______ builds up when you run as fast as you can for as long as you can because your cells cannot get enough oxygen
Lactic acid
Which process requires the suns energy?
Photosynthesis
Photosynthesis is a process that makes ____
Energy from light
What substance is needed to start photosynthesis?
Carbon dioxide
What substance is produced from photosynthesis?
Glucose
In what structure does the process of photosynthesis begin?
The leaves
What is the pigment called inside of the leaves of a plant?
Chlorophyll
The first stage of photosynthesis is using energy to produce sugars
False
In which structure is the chlorophyll located?
Chloroplast
What structure in a leaf brings in carbon dioxide?
Stomata
What is the chemical formula for glucose?
C6H12O6
How many molecules of carbon dioxide (CO2) are needed to start photosynthesis?
6
How many molecules of glucose (C6H12O6) are produced during photosynthesis?
1
How many molecules of oxygen (O2) are produced during photosynthesis?
6
What is needed for photosynthesis?
carbon dioxide, water, and sunlight
Lable the diagram below
Where does photosynthesis occur?
Chloroplast
What are chloroplasts and where are they found?
Organelles found in the leaves of green plants
What are two main functions of chloroplast?
To produce food (glucose) and store food energy
Why do most leaves appear green?
Chlorophyll absorbs most of the colors in the color spectrum and reflects only green and yellow wavelengths of light.
What is the primary pigment found in the chloroplast?
Yellow and green
What is the formula for photosynthesis?
6CO2 + 6H2O + energy --> C6H12O6 + 6O2
Where does the water come from?
soil/roots
Where does the water enter the plant?
roots
Name 3 sources of CO2
living organisms, factory smokestacks, and car fumes
What is produced through photosynthesis?
Glucose
What is glucose used for?
energy
What is oxygen used for?
For living organisms to breathe
Word equation for respiration
glucose + oxygen = carbon dioxide + water+ ATP
chemical equation for cellular respiration
C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
stage one of cellular respiration
Stage one occurs in the cytoplasm, a thick clear gel like structure. 2. Glucose molecules are broken into smaller molecules 3. No oxygen is required at this stage
4. Only a SMALL amount of energy is released from glucose
Stage 2 of cellular respiration
1. Takes place in the mitochondria- a rod shaped structure
2. Small molecules of glucose are broken down even smaller using O2
3. Large amounts of energy are released
4. CO2 and H20 are produced during cellular respiration and are diffused our of the cell
What is a heterotroph?
An organism that cannot make its own food.
What is an autotroph?
An organism that makes its own food
How often does cellular respiration take place?
Continuously
Cellular respiration is the opposite of photosynthesis
True
Fermentation- an energy releasing process that does NOT require oxygen during fermentation cells release energy from food without using oxygen.
...
What are the 2 types of fermentation?
alcoholic and lactic acid
alcoholic fermentation
occurs in yeast
Glucose breaks down to produce alcohol carbon dioxide and energy
Important process in baking and brewing
Performed in yeast and single celled organisms
Does not require energy
Only small amount of energy is produced
lactic acid fermentation
Causes cramps when exercising
Cells in muscles use up oxygen faster than you can breathe
Cells use fermentation to produce energy
Lactic acidosis is produced which is what cause cramping
Performed by heterotrophs
Does not require energy
Only a small amoun
aerobic respiration
Needs oxygen to break down food to release energy
A lot of energy is released
Cellular respiration
anerobic respiration
does not use oxygen for energy
Small amount of energy released
Fermentation
