What is the importance of photosynthesis and cellular respiration?
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
What is the importance of cellular respiration?
The Purpose Cellular Respiration Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function.
What is the importance of photosynthesis?
It’s not oxygen production. The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet’s living systems are powered by this process.
What is cellular respiration essay?
Cellular respiration is the process that is opposite from photosynthesis. While plants are taking in carbon dioxide and water to make sugar and oxygen, cellular respiration uses the oxygen and sugar o make carbon dioxide, water and 36 ATP. Then, two ATP come and are converted to two ADP and two phosphates.
How are photosynthesis and cellular respiration related answers?
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
Why is photosynthesis and cellular respiration described as a cycle?
The relationship between photosynthesis and cellular respiration is often described as cyclic because the products of one process are used as the reactants for the other. Photosynthesis produces carbohydrates from carbon dioxide and water, incorporating light energy into the bonds of the carbohydrates.
How will you describe cellular respiration in your own words?
Cellular respiration is what cells do to break up sugars to get energy they can use. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration.

Respiration occurs in the mitochondria of the cell of the human body. Breathing occurs through lungs….
The main purpose of photosynthesis is to convert radiant energy from the sun into chemical energy that can be used for food. Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.
What is anaerobic respiration reaction?
Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.
What are some examples of anaerobic respiration?
Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation and in decomposition of organic matter. The equation is: glucose + enzymes = carbon dioxide + ethanol / lactic acid. Though it does not produce as much energy as aerobic respiration, it gets the job done.
What is the purpose of 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 two types of anaerobic respiration?
Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration. There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.
What are the steps of anaerobic respiration?
This process occurs in three major stages one intermediate stage: glycolysis, oxidation of pyruvate, the Krebs cycle, and electron transport. The latter two stages require oxygen, making cellular respiration an anaerobic process.
What are the 3 stages of anaerobic respiration?
The reactions of cellular respiration can be grouped into three stages: glycolysis, the Krebs cycle (also called the citric acid cycle), and electron transport. Figure below gives an overview of these three stages, which are also described below.
What is another word for anaerobic respiration?
fermentation
What is the difference between aerobic and anaerobic respiration?
Aerobic: Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. (glucose + oxygen -> carbon dioxide + water). Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen.
Where does anaerobic respiration occur?
Anaerobic respiration (both glycolysis and fermentation) takes place in the fluid portion of the cytoplasm whereas the bulk of the energy yield of aerobic respiration takes place in the mitochondria.
What does the term anaerobic mean?

Aerobic respiration takes place in the presence of oxygen, produces a large amount of energy. Carbon dioxide and water are produced as the waste products. Anaerobic respiration takes place without the use of oxygen, produces small amounts of energy.
What are the end products in respiration?
The products of cellular respiration are carbon dioxide and water. Carbon dioxide is transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled. ATP is generated in the process.
Is alcohol a product of anaerobic respiration?
In the case of anaerobic respiration, glucose is broken and the products generated from this are energy and either lactic acid or ethanol (alcohol) and CO2. This process is termed as fermentation. In muscle, the product of anaerobic respiration is lactic acid. In yeast, it is ethanol.
Why is anaerobic respiration bad?
Anaerobic respiration is considered bad for the human body because this process takes place in the absence of oxygen and lactic acid is produced instead of carbon dioxide and water. The lactic acid is harmful to the body; its accumulation within the muscles leads to painful muscle cramps and fatigue.

What foods use anaerobic respiration?
If you lack interest in organisms, such as yeast and bacteria, which have “stuck with” the anaerobic tradition, the products of these chemical reactions may still intrigue you. Fermentation makes bread, yogurt, beer, wine, and some new biofuels.
Which type of respiration is most efficient?
Aerobic respiration
What type of respiration does yeast perform?
The yeast simply switches from aerobic respiration (requiring oxygen) to anaerobic respiration (not requiring oxygen) and converts its food without oxygen in a process known as fermentation.
How is glucose used in respiration?
Glucose is the molecule normally used for respiration – it is the main respiratory substrate . Glucose is oxidised to release its energy, which is then stored in ATP molecules. Aerobic respiration breaks down glucose and combines the broken down products with oxygen, making water and carbon dioxide.
What happens when glucose enters the bloodstream?
The stomach and small intestines absorb the glucose and then release it into the bloodstream. Once in the bloodstream, glucose can be used immediately for energy or stored in our bodies, to be used later. However, our bodies need insulin in order to use or store glucose for energy.
Does photosynthesis use glucose?
In photosynthesis, solar energy is harvested and converted to chemical energy in the form of glucose using water and carbon dioxide.
What is the role of glucose?
Glucose comes from the Greek word for “sweet.” It’s a type of sugar you get from foods you eat, and your body uses it for energy. As it travels through your bloodstream to your cells, it’s called blood glucose or blood sugar. Insulin is a hormone that moves glucose from your blood into the cells for energy and storage.
