The Respiratory System, Cellular Respiration, Energy, and Photosynthesis
Terms in this set (27)
Rules of The Respiratory System
Breathing and respiration are NOT the same thing!! Breathing is only part of respiration
Inhaling O2 and exhaling CO2
The chemical reaction that releases energy from food
The Respiratory system
A group of organs that take in oxygen and releases carbon dioxide
Organs of the Respiratory System
Larynx (contains vocal cords)
Bronchi (branches to each lung)
Bronchioles (small branches of bronchi)
Alveoli (tiny air sacs)
Diaphragm (dome shaped muscle)
How does O2 enter your body?
When you inhale, your diaphragm contracts and pulls downward. This sucks air containing oxygen into your lungs.
How does CO2 leave your body?
When you exhale, your diaphragm relaxes and moves upward. This pushes the air containing carbon dioxide back out.
Breathing and Cellular Respiration
Breathing brings oxygen into the body. This oxygen is transported by red blood cells to the mitochondria of each cell where it is used to release energy from glucose molecules. The formula for this reaction is 6O2 + C6H12O6 - ATP (energy) + 6CO2 + 6H2O. Water and carbon dioxide are also released.
An inflammation of the bronchioles that cause airways to narrow. This makes it hard to breathe because you can't get air into or out of the lungs.
An inflammation of the lungs usually caused by a bacteria or a virus. Inflamed alveoli can fill with fluid, and you cannot breathe i enough oxygen.
Happens when the alveoli in the lungs are damaged, so oxygen is not transferred from the red blood cells properly. Caused by smoking.
Make their own food through photosynthesis
Get their food by eating other organisms
Special consumers that feed on dead or decaying material
Simple sugar molecules
Organelles that produce energy for cells
The process by which cells use oxygen to release energy from food.
Mitochondria use oxygen to break these glucose molecules apart.
In the process, ATP (the energy cells need to function) is released
All plants and animals use Cellular Respiration
Respiration is not just about breathing. Breathing brings in the oxygen we need for Cellular Respiration to happen and then releases the carbon dioxide we don't need afterward.
The chemical formula for respiration
C6H12O6 + 6O2 - 6CO2 + 6H2O + ATP
Glucose + Oxygen - Carbon Dioxide + Water + Energy
The process by which producers (plants, algae,and some bacteria) use sunlight, carbon dioxide, and water to make food.
This food is a simple sugar called GLUCOSE
Plants capture light energy from the sun in green organelles called Chloroplasts.
This energy is used to change carbon dioxide and water molecules into sugar and oxygen.
Plants capture light energy from the sun in green organelles
The chemical formula for Photosynthesis
6CO2 + 6H2O + Sunlight - C6H12O6 + 6O2
Carbon Dioxide + Water + Energy - Glucose + Oxygen
How are respiration and photosynthesis related?
What one reaction needs to begin, the other reaction produces.
Respiration needs oxygen - that is produced during Photosynthesis.
Photosynthesis needs carbon dioxide - that is produced during respiration
What happens if cells run out of oxygen?
They produce energy through Anaerobic Respiration
This process does not produce as much ATP (energy) as Cellular Respiration
This process produces Lactic Acid
The process of producing energy without using oxygen
A chemical that causes muscles to ache after exercise
Need energy for life processes
Get energy from food
