When cells break down food molecules, some of the energy is ___

Released as heat or stored temporarily in ATP

ATP is a what with 2 extra energy-storing phosphate groups?

Nucleotide

The energy of ATP is released when ____

The bonds that hold the phosphate groups are broken

Breaking these bonds require

An input of energy

You get energy from the food you eat

TRUE

Almost all the energy in living systems needed for metabolism comes
from the sun

TRUE

Biochemical pathways are a series of reactions where the product of
one reaction is the reactant of the next

TRUE

Only autotrophs are capable of photosynthesis

TRUE

Both autotrophs and heterotrophs perform cellular respiration to

When all colors are absorbed, the object appears black

TRUE

Chlorophyll is the most common pigment in plants and algae

TRUE

Cellular respiration occurs in the cytoplasm and in the mitochondria

TRUE

The process by which light energy is converted to chemical energy

Photosynthesis

Organisms that use energy from sunlight or from chemical bonds in
inorganic substances to make organic compounds
