cellular respiration
the process by which cells and some organisms release energy from sugar in the presence of oxygen
How are glucose molecues moved into a cell
carrier proteins use energy when moving molecules into and out of a cell
consumers
oransims that can make thier own food
after proteins are made by ribosomes how do they leave the cell
proteins are packages by Golgia Bodies and they have too cell membrane they they fust to the cell membrane and are released into the cell
diffision
the movement of molecues from where they are concentrated to where they are less concentrated
what is a selectively permeable membrane
it allows somethings to pass through but others not to
How do producers make thier own food
the change light energy into chemical enrgy
endocytosis
a process by which cells transport a large body such as a large protein molecue through the cell membrane into the cytoplasm
What are the end products of respiration
the relase of stored energy
equillimbrum
condition in which the number of molecules of a substance is maintained at the same amount throughout a space
What process occurs in the mitochondria
respiration
exocytosis
a process by which a cell moves large molecules throughout the cell membrane
The green pigment in planst that traps radiant energy from the sun is called
Chlorophyll
fermentation
a process by which yeast and some bacteria are release energy needed for life processes by breaking down glucose into alchol and carbon dioxide
During photosynthesis plants produce glucose and give off
oxygen
lipid
an organic compound that stores or releases large amounts of energy or fats or oils
the enrgy used by all living things starts with
sunlight
metabolism
all of the changes in an organism that enable to live grow and reproduce
during respiration some enrgy is lost as
heat
neucleic acids
large organic molecules that store important information in cells and direct their activties two types are DNA RNA
fermentation gives off energy without using
oxygen
osmosis
the passive transport of water through a cell membrane by diffision
when muscles are overworked, soreness is caused by the build up of
lactic acid
Passive Transport
movement of materials through a cell membrane without the use of energy
photosynthesis
a chemical reaction used by producers such as green plants to produce food light energy is used tto produce chemical energy converting carbon dioxide
producers
green plants that make their own food by photosyntheseis
proteins
organic compound made up of amino acids used throughout the body for growth and to replace and repair cells
