biology unit 1 - photosynthesis vs. cellular respiration.

photosynthesis.

the process of plant growth.

absorb energy from light and stores it in the bonds of glucose.

reactants of photosynthesis.

carbon dioxide (CO2)

water (H2O)

products of photosynthesis.

oxygen (O2)

glucose (C6 H12 06)

chlorophyll.

absorbs light energy to use in photosynthesis.

conversion of energy. (photosynthesis)

light energy converted to energy stored in glucose (C6 H12 O6)

conservation of energy. (photosynthesis)

energy is still there, just in a different form.

ex : light → glucose (C6 H12 O6)

conversion of matter. (photosynthesis)

atoms in reactants break apart from each other and rearrange, forming the products.

conservation of matter. (photosynthesis)

all atoms in reactants are found in the products. (and vice-versa)

cellular respiration.

recharges the “battery” of ATP using energy from glucose.

break down glucose and transfer that stored energy into ATP.

reactants of cellular respiration.

oxygen (O2)

glucose (C6 H12 O6)

products of cellular respiration.

carbon dioxide (CO2)

water (H2O)

conversion of energy. (cellular respiration)

the energy of glucose is transferred to ATP.

conservation of energy. (cellular respiration)

the energy stored in the bonds of the glucose molecule isn’t lost.

conversion of matter. (cellular respiration)

the atoms in the reactants have been rearranged to form the products.

conservation of matter. (cellular respiration)

all of the atoms in the reactants are still present in the products.

chemical equation for photosynthesis.

6CO2 + 6H2O → C6 H12 O6 + 6O2

chemical equation for cellular respiration.

C6 H12 O6 + 6O2 → 6CO2 + 6H2O

carbohydrates

• glucose + other sugars

• short term / quick energy

• your bodies first choice for fuel

• CHO (carbon, hydrogen, oxygen)

lipds.

• fats

• long term energy

• your bodies second choice for fuel

• CHO (carbon, hydrogen, oxygen)

proteins.

• muscle fibers, enzymes, antibodies

• does the work in cells

• ex : “construction workers”

• CHON (carbon, hydrogen, oxygen, nitrogen)

nucleic acids.

• DNA and RNA

• tells cells what to do

• ex : “construction supervisors”

• CHONP (carbon, hydrogen, oxygen, nitrogen, phosphorus)
