What uses oxygen and food to make energy for the cell?
Every cell of the body needs oxygen for the process of cellular respiration by which 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 happens when oxygen combines with food?
Explanation: During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. They release the carbon dioxide into the air as a waste product.
What does oxygen combine with to give us energy?
When molecular hydrogen (H2) and oxygen (O2) are combined and allowed to react together, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide. These two processes are represented by the two chemical equations shown at right.
Where do food and oxygen get converted into energy?
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.
How does oxygen produce energy?
Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.
What form of energy does food provide for your body?
We get chemical energy from foods, which we use to run about, and move and talk (kinetic and sound energy). Chemical energies are stored in fuels which we burn to release thermal energy – this is one way of making electricity, see Electricity for more information.
What turns food into energy in a cell?
The mitochondria are the converters; they convert the fuel into useable energy. When food is digested, or broken down into its smallest molecules and nutrients, and air is taken in, or inspired, the smallest molecules and nutrients cross into the bloodstream.
Is it possible to use oxygen to generate energy?
Yes we can use oxygen to generate energy. Pure oxygen can combine with materials such as carbon to produce carbon dioxide during the burning process. In fact we burn the food we eat similarly to give us the energy to do work.
How does cellular respiration get energy from food?
Cellular respiration—a biological version of internal combustion—is the main way that chemical energy is harvested from food and converted to ATP energy (see Figure 5.6). Cellular respiration is an aerobicprocess, which is just another way of saying that it requires oxygen.
What do cells do with the energy they get from oxidation?
Cells do not use the energy from oxidation reactions as soon as it is released. Instead, they convert it into small, energy-rich molecules such as ATP and nicotinamide adeninedinucleotide(NADH), which can be used throughout the cell to power metabolism and construct new cellular components.
Where do cells get the energy they need to function?
Cells need energy to accomplish the tasks of life. Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
