Photosynthesis, Cellular Respiration, and Fermentation Science Test

What is cellular respiration?

Breaking food down to get energy

What is a major source of energy for cellular respiration?


What substance is needed to carry out respiration?


What are all the products of cellular respiration?

Carbon Dioxide, water, and energy

Plants do not use the process of cellular respiration.


What many stages are their in cellular respiration?


Where does the first stage of cellular respiration take place?


Where does the second stage of cellular respiration take place?


Fermentation is an adaption to an environment that..

Has a small amount of no oxygen

Alcohilic fermentation is important to bread rising


______ 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 is a process that makes ____

Energy from light

What substance is needed to start photosynthesis?

Carbon dioxide

What substance is produced from photosynthesis?


In what structure does the process of photosynthesis begin?

The leaves

What is the pigment called inside of the leaves of a plant?


The first stage of photosynthesis is using energy to produce sugars


In which structure is the chlorophyll located?


What structure in a leaf brings in carbon dioxide?


What is the chemical formula for glucose?


How many molecules of carbon dioxide (CO2) are needed to start photosynthesis?


How many molecules of glucose (C6H12O6) are produced during photosynthesis?


How many molecules of oxygen (O2) are produced during photosynthesis?


What is needed for photosynthesis?

carbon dioxide, water, and sunlight

Lable the diagram below

Where does photosynthesis occur?


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?


Where does the water enter the plant?


Name 3 sources of CO2

living organisms, factory smokestacks, and car fumes

What is produced through photosynthesis?


What is glucose used for?


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?


Cellular respiration is the opposite of photosynthesis


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
