Body Cells
What happens to glucose molecules during respiration?
React with Oxygen to Release Energy
What is the chemical formula for the breakdown of glucose during respiration?
$C6H_{12}O6 + 6O2 \rightarrow 6CO2 + 6H2O + Energy$
Do plants respire by taking in oxygen and giving out:
$CO2$
Which process occurs when oxygen breaks down food to release energy?
Respiration
During respiration, the nutrients of the digested food react with nitrogen in the body cells to release energy.
False
Internal respiration occurs in the lungs of living organisms.
False
Plants do not respire like animals by taking in oxygen.
False
External respiration involves inhaling air rich in carbon dioxide and exhaling air rich in oxygen.
False
The chemical reaction involved in respiration includes breaking down glucose into oxygen and water.
False
Respiration is the process of releasing energy from food by oxidation.
True
