when energy-rich molecule produced by cellular respiration directly powers cell work?
ATP
which of the following is a common energy currency in living cells that powers most living organisms?
ATP
how does CO2 enter a plant
through the stomata
which processes can be carried out by producers?
both photosynthesis and cellular respiration
the reason this organelle is green is because of the pigment _____________, which is the light-absorbing molecule of this organelle
chlorophyll
the entire organelle shown in the image is called a _______
chloroplast
which molecule is broken down in cellular respiration, providing fuel for the cell?
glucose
identify the stage of cellular respiration when glucose is split into two molecules of pyruvic acid?
glycolysis
which processes take place in the cytocol of a eukaryotic cell?
glycolysis
select the correct sequence of steps as energy is extracted from glucose during cellular respiration
glycolysis to acetyl CoA to citric acid cycle to electron transport chain
One of the "stacks of pancakes" is called a _____________
granum
how do we know green light is not absorbed by chlorophyll
green light is the wavelength of light that is reflected instead of absorbed by the chloroplasts
in cellular respiration, most energy is released and transferred to ATP when ________
high-energy electrons "fall" to lower energy levels
the outside of this organelle is surrounded by a double layer of ______
membrane
which of the following is highest in chemical energy?
one molecule of glucose
the gases needed as inputs for photosynthesis enter the plant through small pores called _______
stoma
kinetic energy is energy in motion. Potential energy is __________ energy
stored
name the fluid-filled interior of the chloroplast?
stroma
the thick fluid inside this organelle is where many of the reactions of photosynthesis take place. this fluid is called ____________
stroma
describe the citric acid cycle?
this process produces some ATP and carbon dioxide in the mitocondrion
one of the single pancake-like discs in this organelle is called a ______
thylakoid
identify the principal role of cellular respiration
to convert the chemical energy of sugars into the chemical energy that fuels life's processes
energy is conserved. this means that in any system ________
total energy input equals total energy output
which of the following best describes the chemical equation for photosynthesis
water + carbon dioxide + energy = sugar + oxygen
