What is the word equation for aerobic respiration?
oxygen + glucose –> carbon dioxide + water
What is the chemical formula for glucose?
C6H12O6
The concentration of glucose in the blood is controlled by homeostasis.
Give one other example of an internal condition controlled by homeostasis.
Temperature, water levels, salt, pH, oxygen levels
What are some physical responses your body has to becoming too cold?
Shivering, Goosebumps, vasoconstriction
What are some physical responses your body has to becoming too hot?
Sweating, panting, vasodilation
Which organ does asthma affect? What are some symptoms?
The lungs. Symptoms such as coughing, wheezing, chest tightness, or shortness of breath.
How does smoking affect the gas exchange system in the lungs?
Many chemicals in tobacco smoke and tar destroy cilia, which causes mucus to start to build up in the small airways making it harder for your to breathe.
Anaerobic respiration formula:
Glucose —> lactic acid
Why does yeast make bread rise?
The dough with yeast rises because yeast is a living organism that can respire aerobically. Since the yeast has access to an energy store (sugar) and oxygen, it will respire aerobically. The waste product carbon dioxide is produced and gets trapped inside the dough. This then stretches and pulls at the dough using the air bubbles of the dough make the dough rise.
How are stitches caused?
When your body can’t get enough oxygen, it will start to respire anaerobically creating the waste product lactic acid. This then causes the pain of stitches, since the lactic acid can not be rid of quickly.
