Respiration and Glucose Flashcards
give 6 uses for glucose
fats or oils for storage respiration combine with nitrates to make protein cellulose for cell walls stored as insoluble starch amino acids
why is glucose stored as fats or oils
if there’s no photosynthesis, plant can still grow
why is glucose used in respiration
to produce energy
why does glucose combine with nitrates
to make proteins for growth and repair
why is glucose used as cellulose in cell walls
to strengthen cell wall
why is glucose stored as insoluble starch
so it doesn’t draw water into plant cells and can be broken down when no light
why is glucose used as amino acids
for protein synthesis
what happens in cellular respiration
transfers glucose into energy , an exothermic reaction that continuously occurs in living cells
how do organisms used energy releases by respiration (3)
to build larger molecules ( enzymes)
muscular contractions
maintaining body temperature
describe aerobic respiration
continuous reacting in living cells using oxygen; it occurs in. mitochondria and fully breaks down glucose
describe anaerobic respiration
respiration without oxygen and is an incomplete breakdown of glucose
which type of respiration is the most efficient
aerobic
what is the equation for aerobic respiration
oxygen + glucose -> carbon dioxide + water +energy
what is the symbol equation for aerobic respiration
6O2 + C6H12O6 -> 6H2O + 6CO2 + energy
what is the word equation for anaerobic respiration in animals
glucose -> lactic acid + small amount of energy
what is the word equation for anaerobic respiration in plants
glucose -> ethanol + carbon dioxide
what is anaerobic respiration in plants called
fermentation
give two uses for fermentation in yeast cells
making bread
making alcohol
what does OGRE stand for and when is it used
oxygen glucose respiration energy used to describe respiration
what is the first step in investigating the effect of exercise in heart rate
collect a large sample size of people with the same sex , age and lifestyle factors to ensure reliability
what is the second step in investigating the effect of exercise on heart rate
measured the heart rate of the participants for 1 minute
what is the third step in investigating the effect of exercise on the heart rate
get participants to do 50 star jumps in 30seconds (any exercise in any amount of time)
what is the fourth step in investigating the effect of exercise on the heart rate
record heart rate after exercise and repeat for reliability
