Unit 4 Flashcards
what molecule provides a quick source of energy for cellular activities
ATP
how can atp be recharged
by adding a third phosphate group
what is energy
the ability to do work
example of chemical energy
battery
example of mechanical energy
hammering a nail
example of electrical energy
lightning
example of thermal energy
warmth from the sun
five daily activities cells need energy for
movement, growth, dividing, membrane transport, making proteins
what os the difference between a autotroph and heterotroph
autotrophs make their own food and heterotroph have to hunt/ find it
two examples of autotrophs
algae and grass
two examples of heterotrophs
humans and bears
why is glucose a better energy store for cells than atp
the breakdown of one glucose molecule is enough to make 38 atp molecules
chemical equation for photosynthesis
CO2 +H20 = C6H12O6 + O2
What part of a plant cell is responsible for photosynthesis
chloroplasts
why ate most plants green
chlorophyll is a pigment that gives them the green color
what three factors affect the rate of photosynthesis
amount of light, amount of water, temperature
why is photosynthesis important for life on earth
it is the foundation of the food chain
what is the chemical reaction for respiration
C6H12+ 6O2 = 6CO2 +6H2O + ATP
what is the difference between aerobic and anaerobic respiration
aerobic uses oxygen and anaerobic does not
what are two types of anaerobic respiration
alcoholic fermentation and latic acid fermentation
what are the products of anaerobic respiration
latic acid, carbon dioxide and alcohol
what is number 1
the
sun/light energy
what is number 2
what is number three
