respiration Flashcards
give the four main reasons that energy is stored in cells
cell division
movement
maintaining body temperature
chemical reactions
what are 2 ways that energy is stored in cells
carbohydrates
fat
when might new cells be produced
for growth or to replace cells
where is the energy for germination stored in seeds?
in what form is this energy stored?
food stores.

2) cold blooded animal
3) carnivorous plant
1) birds
2) fish

name a chemical reaction that occurs in plant cells
photosynthesis
what is respiration
enzyme controlled reactions which releases chemical energy stored in glucose
oxygen present
aerobic respiration - each pyruvate broken down to CO2 and H2O releasing energy to yield ATP molecules
glucose + oxygen —> carbon dioxide + water + energy
oxygen absent in plant and yeast cells
fermentation - products of fermentation are different from plant and yeast
glucose —> ethanol + carbon dioxide + energy
oxygen absent in animal cell
pyruvate molc from glucose are converted to lactate
glucose —> lactate + energy
aerobic respiration equation
glucose + oxygen —> carbon dioxide + water + energy
fermentation in plant and yeast equation
glucose —> ethanol + carbon dioxide + energy
fermentation in animal cell equation
glucose —> lactate + energy
ATP stands for…
adenine triphosphate
