Human cells obtain energy by a process called respiration. This process is carried out in organelles in the cell called the Mitochondria. A Mitochondrion uses Glucose and Oxygen this reaction to form its two waste products, carbon dioxide and water, with the useful by product of energy, in the form of something called 'ATP'. Unless you are above the age of sixteenish, you will not need to know what ATP is, or even that it exists.
The word equation for respiration is:
Glucose + Oxygen → Carbon Dioxide + Water (+ Energy)
The last part in brackets is sometimes excluded.
The symbol equation is:
C6H12O6 + 6 O2 → 6 CO2 + 6 H2O
Due to the fact that energy has no chemical value, it is excluded from this equation universally.
This explanation is rather long, and I wrote it for intention of the asker reading it and taking interest. Of course, in the unfortunate circumstance in which you could not care less about all the time I have taken to answer this question in detail for you, the simple and boring one sentence answer is:
Human cells obtain energy via the process of Respiration (which takes place in the Mitochondria of the Cells). Depending on your year/grade, you may want to exclude/include the last part.
Good Luck!
Cellular respiration breaks down glucose in order to make energy (ATP).
Cellular respiration needs glucose. Glucose is produced by photosynthesis
can be changed into glucose and used in cellular respiration.
Yes - glucose is broken down in the first step of cellular respiration. This stage is known as glycolysis and occurs in the cytoplasm. Cellular respiration begins with glucose and ends creating ATP.
Because the reactants required for cellular respiration (glucose and oxygen) are the products ofphotosyntheses And the and the products of cellular respiration (carbon dioxide and water) are the reactants of photosynthesis.
Oxygen is required for cellular respiration, because it is one of the ingredients needed for the metabolic reaction to occur, along with glucose.
The raw materials needed for cellular respiration are glucose (sugar) and oxygen. Glucose is obtained from the breakdown of carbohydrates in our diet, while oxygen is obtained through respiration. These two molecules are needed to produce energy in the form of ATP through the process of cellular respiration.
Cellular respiration requires both glucose and oxygen. Glucose provides the energy for the cell and oxygen is required to be the final electron acceptor so that aerobic respiration can happen. Other molecules can enter cellular respiration and be broken down, but glucose is considered the start of this process. Oxygen is also not required, but if it is not present, then fermentation will run and this process is not nearly as efficient as aerobic respiration.
Cellulr respiration requires glucose and oxygen and produces carbon dioxide, water and energy
Cellular respiration breaks down glucose in order to make energy (ATP).
Cellular respiration needs glucose. Glucose is produced by photosynthesis
Cells need glucose and oxygen as starting materials for cellular respiration. Glucose is the primary source of energy, while oxygen is required as the final electron acceptor in the electron transport chain to generate ATP.
can be changed into glucose and used in cellular respiration.
Carbon skeletons for cellular respiration can be obtained from glucose, fatty acids, and amino acids. These molecules are broken down in different metabolic pathways to generate energy in the form of ATP.
Glucose and oxygen enter a cell's cytoplasm for aerobic cellular respiration.
Yes - glucose is broken down in the first step of cellular respiration. This stage is known as glycolysis and occurs in the cytoplasm. Cellular respiration begins with glucose and ends creating ATP.
cellular respiration is preformed when the cells need to obtain energy from glucose.
