What is the process called by which plants turn light energy into chemical energy?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Which of the following word equations describes the reaction that organisms use to provide energy for life’s processes cellular respiration )?
Item EB024002: The reaction glucose + oxygen carbon dioxide + water provides organisms with energy for life processes.
What converts chemical energy into cellular energy?
Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
What is the equation for photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What is the equation for photosynthesis and cellular respiration?
The products of one process are the reactants of the other. Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O.
What is the word equation for photosynthesis Class 7?
Answer: carbon dioxide + water —> glucose + oxygen + wate it can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2.
What is the importance of photosynthesis Class 7?
Photosynthesis helps to maintain a balance between oxygen and carbon dioxide in the atmosphere as it absorbs carbon dioxide and releases oxygen. Sunlight is necessary for photosynthesis. Thus sun is the ultimate source of energy for all living organism. Our earth is the unique planet, where photosynthesis takes place.
What are the products of photosynthesis Class 7?
Glucose and oxygen are the final products of photosynthesis. We all know that photosynthesis is a process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.
What is the formula for respiration?
The word equation for respiration is: Glucose + Oxygen = Carbon Dioxide and Water The chemical equation is C6H1206 + O2 = CO2 + H20 Respiration is used by all living humans and animals, to make energy for movement, heat and to keep vital organs running, without it we’d be dead.
What is the chemical equation of anaerobic respiration?
Anaerobic respiration takes place in the cell cytoplasm and produces lactic acid. The chemical equation is C6H12O6 -> 2C3H6O3 (Glucose -> Lactic acid).
What is word equation for aerobic respiration?
Respiration: Glucose + Oxygen –> Water + Carbon Dioxide + EnergyIf there is a lack of oxygen then anaerobic respiration will take place instead of aerobic respiration, which in animals has the following word equation:Glucose –> Lactic Acid + Some energy This releases less energy than aerobic respiration and produces …
What is the example of anaerobic pathway?
Under anaerobic conditions, the absence of oxygen, pyruvic acid can be routed by the organism into one of three pathways: lactic acid fermentation, alcohol fermentation, or cellular (anaerobic) respiration. Humans cannot ferment alcohol in their own bodies, we lack the genetic information to do so.
What is another name for anaerobic respiration?
The other name for anaerobic respiration is fermentation.
How do you explain anaerobic respiration?
Definition. Anaerobic respiration is the type of respiration through which cells can break down sugars to generate energy in the absence of oxygen. This is in contrast to the highly efficient process of aerobic respiration, which relies on oxygen to produce energy.
What are the steps of anaerobic cellular respiration?
Aerobic vs anaerobic respiration
| Aerobic | Anaerobic | |
|---|---|---|
| Location | Cytoplasm (glycolysis) and mitochondria | Cytoplasm |
| Stages | Glycolysis (anaerobic), Krebs cycle, oxidative phosphorylation | Glycolysis, fermentation |
| ATP produced | Large amount (36 ATP) | Small amount (2 ATP) |
What is the main product of anaerobic respiration?
Aerobic respiration vs anaerobic respiration
| Aerobic | Anaerobic | |
|---|---|---|
| Oxygen | Needed | Not needed |
| Glucose breakdown | Complete | Incomplete |
| End product(s) | Carbon dioxide and water | Animal cells: lactic acid. Plant cells and yeast: carbon dioxide and ethanol |
| Energy released | Relatively large amount | Relatively small amount |
What are the disadvantages of anaerobic respiration?
Disadvantages: Anaerobic respiration generates only two ATPs and produces lactic acid. Most lactic acid diffuses out of the cell and into the bloodstream and is subsequently absorbed by the liver. Some of the lactic acid remains in the muscle fibers, where it contributes to muscle fatigue.
What are the benefits of cellular respiration over anaerobic respiration?
Summary. Aerobic and anaerobic respiration each have advantages under specific conditions. Aerobic respiration produces far more ATP, but risks exposure to oxygen toxicity. Anaerobic respiration is less energy-efficient, but allows survival in habitats which lack oxygen.
Which of these are needed for anaerobic cellular respiration?
In aerobic respiration oxygen (O2) is needed and in anaerobic respiration no oxygen needed. Aerobic produces 36 ATP; Anaerobic produces 2 ATP.
What is the main advantage of aerobic cellular respiration?
A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can just split glucose into two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.
