photosynthesis Flashcards
What does the human gas exchange system allow us to do
Get oxygen we need and to remove the waste carbon dioxide we do not need
What is ventilation
It involves the movement of the ribs intercostal muscles and diaphragm to move air into and out of the lungs
What is respiration
A chemical reaction that happens in all living cells
What is anaerobic respiration
During hard exercise not enough oxygen can reach your muscle cells so aerobic respiration is replaced with anaerobic respiration
What’s the word equation for anaerobic respiration in humans
Glucose to lactic acid
What are the differences between aerobic and anaerobic
Aerobic respiration releases more energy per glucose molecule than anaerobic respiration
What products does aerobic form
Carbon dioxide and water
What products does anaerobic form
Lactic acid
What’s the word equation for aerobic respiration
Glucose plus oxygen = carbon dioxide + water
What are protons used for
To make cells
What does respiration do
Releases energy used to grow
What is chlorophyll
It’s the green pigment in the leaves
What is upper epidermis
It has a waxy cuticle for protection and to prevent water loss
What does palisade mesophyll do
Carries out photosynthesis so cells a patch with chloroplast
What does spongy mesophyll do
It has a large surface area for gas exchange
