How do animals break down sugars?
Plants form glucose by photosynthesis and animals get glucose by breaking down the food they eat. During cellular respiration, glucose combines with oxygen to release energy and to form carbon dioxide and water. Most of the carbon dioxide in animals is released into the air when the animal breathes.
What is the name of the process where animal cells break down sugar?
cellular respiration
During cellular respiration, sugar is burned in the presence of oxygen to produce energy in the mitochondria of the cell.
What do animals release when they break down metabolize sugars?
Animal metabolism, therefore was a simple, one-way flow of food that began with the intake of proteins and carbohydrates and ended with the excretion of carbon dioxide and urea. Energy is released and stored as ATP, and eventually the remnants of the sugar molecule become alcohol and carbon dioxide.
Which process involves the breakdown of sugar?
This process results in the production of energy for the cell.
What uses sunlight for sugar?
Chlorophyll [Pigment]in the chloroplasts [Organelle] helps the plants to make their food. Therefore, chloroplasts are the organelles in the plant cell that use the sun’s energy to make sugar.
What is the first step of respiration?
glycolysis
The first stage of cellular respiration, called glycolysis , takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.
What is a role of carbohydrates in animal cells?
Carbohydrates are the basic energy source in animal cells. Dietary carbohydrates obtained from plant-based products serve as a major source of energy for the animal.
What part of animal cell breaks down sugar to release energy?
What part of an animal cell breaks down sugar to release energy? Glycolysis is the first step where glucose is broken down into two molecules of pyruvate. This occurs in the cytoplasm of the cell.
Where does the break down of sugar take place?
The process of breaking down sugar begins in your mouth. When you put a carbohydrate-containing food inside your mouth, enzymes from the saliva in your mouth begin to break down the carbohydrates.
How are glucose molecules broken down in fermentation?
If oxygen is not available to animal cells then pyruvate is converted into lactate (sometimes referred to as lactic acid). In plant and yeast cells pyruvate is converted into carbon dioxide and a type of alcohol called ethanol . This process is called fermentation and yields only two molecules of ATP per glucose molecule broken down.
How are glucose molecules broken down in plants?
As part of plants’ chemical processes, glucose molecules can be combined with and converted into other types of sugars. In plants, glucose is stored in the form of starch, which can be broken down back into glucose via cellular respiration in order to supply ATP.
What part of an animal cell breaks down sugar to release energy? Glycolysis is the first step where glucose is broken down into two molecules of pyruvate. This occurs in the cytoplasm of the cell.
What happens when you break down sugar in a cell?
Breaking down sugar produces the energy your body needs. This is very similar to wood burning in a fire. As the wood burns, it combines with oxygen and releases heat energy and carbon dioxide. When the cell uses oxygen to break down sugar, oxygen is used, carbon dioxide is produced, and energy is released.

How does the body use oxygen to break down sugar?
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.
