Revision Flashcards
What do plant cells have that animal cells dont??
Cell wall, chloroplast, vacuole
Equation for magnification
Eye piece lenses X Magnification
What are animal and plant cells examples of?
Eukaryotic cells
What do eukaryotic cells all have
Cell membrane, cytoplasm and genetic material enclosed in the nucleus
What is the genetic material called?
DNA
equation for aerobic Repiration
Glucose+oygen->carbon dioxide+water
How does the body respond to exercise to get what it needs for respiration?
Increase heart rate
Increase Breathing rate
Increase breathing volume
Increase stoke volume/heart
When you get no oxygenwhile aerobic respiration is
Anaerobic respiration
Anaerobic respiration
(No oxygen) glucose-> lactic acid (muscells clump up)
Diffrence in in anaerobic and aerobic repiration
Does not require oxygen
Incomplete breakdown of glucose
Occurs in cytoplasm during vigorous activities
Less energy released(-20 times less efficient)
Aerobic repiration
Requires oxygen
Complete breakdown of glucose
Occurs in mitochondria during moderate level activities
“Full” energy realesed
The gulucose causes a build up of lactic acid in the muscels and creates
An oxygen debt
What is an oxygen debt
is the amount of extra oxygen the body needs after (anaerobic) exercise to react with the accumulated lactic acid and remove it from the cells.
Rapid and deep breathing (‘panting’) is needed for a short period after high intensity exercise in order to
Repay the oxygen debt
Blood flowing through the muscles transports the lactic acid to the liver where it is…
converted back into glucose.
