B4 bioenergetics Flashcards
what is the word equation for photosynthesis
carbon+ water —-> glucose + oxygen
what does photosynthesis produce
produces glucose using light
what’s the symbol equation for photosynthesis
6CO2+ 6H20 —-> C6 H12 06+ 602
what are uses for glucose in plants
respiration
making cellulose
making amino acids
stored as oils or fats
stored as starch
what are the limiting factors for photosynthesis
intensity of light
concentration of C02
temperature
chlorophyll
what is a metabolism
all the chemical reactions in an organism
how are the ideal conditions for farming created (artificially)
and its negative
- greenhouse
- heater
- artificial lights
- increase level of carbon dioxide
- keeping plants free from pests
expensive
what is respiration
the process of transferring energy from glucose
what are the 3 main uses for respiration
build up larger molecules from smaller molecules (proteins from amino acids)
allow muscles to contract
for a steady body temp
what the equation including light intensity and distance
light intensity= 1 ➗distance (squared)
what’s the difference between aerobic respiration and anaerobic respiration
-requires oxygen
- doesn’t use oxygen
what’s the word equation for aerobic respiration
glucose+ oxygen ——>carbon dioxide +water
what’s the word equation for anaerobic respiration
glucose ——> lactic acid
what’s the word equation for anaerobic respiration in plants and yeast
glucose —> ethanol + carbon dioxide
what happens when you exercise
and long periods of exercise
cause you to respire more,
meaning more oxygen and that oxygenated blood is circulated around the body faster,
removing CO2 faster
long periods can cause fatigue, stop contracting properly
