How do enzymes affect the activation energy of a reaction?
Enzymes lower the activation energy required for a reaction to
proceed, which increases the reaction rate
Various factors can alter the rate of enzyme reactions, for example..
1. Temperature
2. pH*
3. Substrate concentration
4. Enzyme concentration
site of photosynthesis ?
chloroplasts
Two stages of photosynthesis ?
light reactions and calvin cycle
Light reactions occur in the?
thylakoid membrane
Calvin cycle occurs in the ?
Stroma
What is the difference between "Net" and "Gross" photosynthesis?
, Gross Photosynthesis: The total amount of energy/sugar produced by
the plant.
Net Photosynthesis: Gross photosynthesis minus the energy used by
the plant for its own cellular respiration.
Cellular respiration and photosynthesis occur
at the same time
Three basic organs of a vascular plant ?
1. Roots
2. Stem
3. Leaves
Three tissue systems found in every plant organ ?
1. Dermal tissue
2. Vascular tissue
3. Ground tissue
Dermal tissue ?
Outer protective covering
Vascular tissue ?
Conducts water and nutrients
Ground tissue ?
Responsible for metabolic functions like photosynthesis and storage
Whats primary function of the stomata
To facilitate gas exchange (CO2 in, O2 out) for photosynthesis and to
regulate water loss through transpiration
What is the general chemical equation for an enzymatic reaction?
