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
