 Photosynthesis is a chemical reaction that uses carbon dioxide, sunlight, and water to produce sugar and oxygen.

 Reactants are substances needed for a chemical reaction

 Products are substances made at the end of a chemical reaction

The equation for photosynthesis is CO2 + H2O + sunlight energy -> C6H12O6 + O2

 What is the equation for photosynthesis?

Carbon dioxide(CO2), water(H2O) and sunlight energy

What are the reactants for photosynthesis?

What are the products for photosynthesis?

 Chemical energy is transformed from light energy and usable energy is in the form of glucose.

 Label the chemical energy and the usable energy for photosynthesis.

 It’s flattened membrane sac inside chloroplast contain the pigments that can absorb certain wavelengths of sunlight

 It’s fluid portion of the chloroplast (where glucose is made)

 It’s tiny holes on the bottom of the leaf, which allows gas and water vapor exchange to occur.

Light and Pigments: Light isn’t he form of photons is absorbed by …..?

Light and Pigments: Pigment molecules are embedded in the …..?

The most common pigment I. the chloroplast is….?

 Of light- making the leave appear red, yellow, or orange.

In the fall, plants reabsorb chlorophyll leaving other pigments that reflect other wavelengths of….?

It’s light- dependent and light- independent

Photosynthesis has two stages. What are they?

Thylakoid membrane. Water is split  and oxygen is given off.

 Light dependent reactions: sunlight strikes the chlorophyll molecule in the….?

Does not require LIGHT and it’s called the CALVIN CYCLE.

 Light independent reaction: the second phase of photosynthesis does not require BLANK and it’s called the BLANK BLANK. Fill in the blanks.

Uses the carbon dioxide taken in for ENERGY and puts together GLUCOSE molecules

The Calvin cycle uses the carbon dioxide taken in for BLANK and puts together BLANK molecules.

Light energy is absorbed by chlorophyll in the e thylakoid membranes. This energy is then uses to split water molecules into oxygen, hydrogen ions, and electrons in a process called photolysis. The oxygen is released as a byproduct, while the electrons are used to produce ATP and NADPH, which are energy storage molecules used in the Calvin cycle.

What occurs in the light dependent phase of photosynthesis? 

Also know as the Calvin cycle takes place in the stroma of the chloroplast. It uses the carbon dioxide taken in for energy and puts together glucose molecules.

What occurs in the light independent phase of photosynthesis? 

In the fall, plants reabsorb chlorophyll leaving other pigments that reflect other wavelengths of light making the leads appear red, yellow, or orange.

Explain the process that is occurring when leaves change color in the fall.

Without CO2, the plant would not have one of the raw materials needed in the photosynthesis equation.

3 Factors that affect Photosynthesis: CARBON DIOXIDE(CO2)

The temperature must be in the appropriate range for the plant in order for photosynthesis to properly occur.

3 Factors that affect Photosynthesis: TEMPERATURE

If the intensity of light is lower, the available energy for photosynthesis is lower. Lower intensity equals less photosynthesis occurring.

3 Factors that affect Photosynthesis: INTENSITY OF LIGHT

It’s a process that converts oxygen and glucose(SUGAR) into ATP energy.

It’s oxygen(O2) + glucose(C6H12O6) -> ATP + water(H2O) + carbon dioxide(CO2)

What is the cellular respiration equation?

The reactants are Glucose(C6H12O6) and oxygen(O2)

What are the reactants for cellular respiration?

ATP energy, water(H2O) and carbon dioxide(CO2)

What are the products for cellular respiration?

Chemical energy is in glucose and usable energy is in the form of ATP

Label the chemical energy and the usable energy for cellular respiration.

Aerobic respiration and anaerobic respiration 

There are two types of cellular respiration what are they?

The type of energy that’s is used in photosynthesis is NUCLEAR which is sunlight. The produced is CHEMICAL energy.

Which type of energy is used in photosynthesis and which type is produced in photosynthesis?

Cellular respiration in the presence of oxygen is called?

Cellular respiration that does not require oxygen is called?

TRUE OR FALSE: Anaerobic respiration uses oxygen

TRUE OR FALSE: Aerobic respiration uses oxygen

How much ATP does anerobic respiration make?

How much ATP does aerobic respiration make?

TRUE OR FALSE: aerobic respiration is not efficient 

TRUE OR FALSE: anaerobic respiration is efficient

Anaerobic respiration (FERMENTATION) produces….?

Anaerobic respiration(FERMENTATION) is used by yeast and bacteria to create….?

Lactic acid fermentation and alcoholic fermentation

There are two types of anaerobic respiration what are they?

Lactic acid fermentation produces lactic acid(MUCSLES) and alcoholic fermentation produces alcohol(yeast, bacteria cells).

What does lactic acid fermentation and alcoholic fermentation do?

They are related through the flow of energy and matter of ecosystems. The products of photosynthesis which is glucose and oxygen are the reactants of cellular respiration, and vice versa. They form a cycle, with each process providing the raw materials for the other.

How are photosynthesis and cellular respiration related?

Temperature affects cellular respiration because in lower temperatures, respiration slows down impacting enzyme activity and the rate of reaction. In higher temperatures, respiration speeds up, but excessively high temperatures can denature enzymes and disrupt the process.

Describe a factor that would affect cellular respiration and explain how it will be affected.
