study guide 2 Flashcards
formula for photosynthesis
Sunlight+ water+ carbon dioxide–oxygen + glucose
where does photosynthesis occur in plant cells
chloroplasts
light energy is made up of particles called
photons
used to make sugar
ATP
pigment present in the green parts of plants it absorbs photons of light energy
chlorophyll
renewable fuels made from living organisms
fuel from algae
biofuels
how do humans and other animals obtain energy
by eating food
energy stored in the chemical bonds
potential energy
the energy of motion and movement
kinetic energy
obtain energy by eating other organisms
heterotrophs
capture and transform the energy of sunlight by photosynthesis
autotrophs
process by which plants and other autotrophs use the energy of sunlight to make energy rich molecules; uses carbon dioxide and water and sunlight
photosynthesis
chronic undereating; the child lacks nutrients necessary for the chemical reactions of growth and development
malnutrition
all of the chemical reaction that happen in your body
metabolism
break down larger structures into smaller ones
catabolic reactions
bond building; build new structures from smaller subunits
anabolic
helper molecules; proteins that speed up chemical reactions
enzymes
the process of speeding up the rate of a chemical reaction by enzymes
catalysis
part of an enzyme that bind to the substrate
active site
molecule to which an enzyme binds and on which it acts
substrate
proteins that speed up chemical reactions
enzymes
energy required for a chemical reaction to proceed
activation energy
