Which macromolecule will the body never break down when it needs energy?
Nucleic Acid
Which organisms in a food chain use energy from the sun to make their own food?
Producers
The process through which autotrophs convert solar energy to chemical energy
This type of biomolecule speeds up chemical reactions by lowering activation energy.
enzyme
What part of the cell makes lipids?
smooth er
Movement of water across a membrane is called what?
Osmosis
In the absence of oxygen, what does yeast produce?
CO2 and Alcohol
This organelle in plants contains chlorophyll.
Chloroplast
This term refers to the specific molecule an enzyme acts upon.
substrate
This process occurs when the cell uses energy to bring something in from outside the cell.
endocytosis
Organisms that break down dead material and recycle nutrients are:
decomposers
Overall, photosynthesis is a reaction that...
is endothermic
Double Points
Of the three stages of respiration, this one produces the most ATP.
Bonus, where does this happen in plants and animal cells?
Electron transport chain
Inner folds of the mitochondria. Thylakoid membrane of the chloroplast
A student notices that a reaction speeds up as temperature rises, until the enzyme changes shape and stops working. This loss of shape is called what?
denaturation
If a cell has 36 chromosomes, how many chromosomes will each of its daughter cells have after mitosis?

Energy is released from an ATP molecule for cellular processes when it...
looses a phosphate group
During photosynthesis, what is the primary role of ATP and NADPH produced in the light-dependent reactions?
to transfer energy to the calvin cycle
Explain why mitochondria have many folded inner membranes.
to increase surface area for ATP production in the ETC
The location where an enzyme binds to the substrate is known as its...
active site
Only about this percentage of energy transfers from one trophic level to the next.

At the beginning of cellular respiration ____________________________ occurs in the cytoplasm
In an exothermic reaction, this happens to energy.
Energy is released
