B3 - Metabolism

photosynthesis

stores solar energy in chemical bonds(charging)

respiration

releases stored energy for use

energy generation steps

1) glycolysis

2)energy release: fermentation or cellular respiration

cellular respiration, whole plant level, structure

all live cells of any organism.

cellular respiration, whole plant level, function

respiration takes place 24/7 to power metabolic activities

cellular respiration, cell level, structure

cell has cytoplasm, organelles, and mitochondria

cellular respiration, cell level, function

Breck down polysaccharides to smaller sugars, break down again for energy

cellular respiration, mitochondrian scale, structure

mitochondria are organelles in cytoplasm, inner membrane studded with location where respiration occurs.

cellular respiration, mitochrondrian scale, function

products of glycolysis are broken further down to release energy and CO2

metabolism

sum of all of the interrelated biochemical processes that occur in an organism.

biomass allocation

distribution of plant biomass among different organs and tissues.

tradeoff

when one trait cannot increase without another trait decreasing.

metabolism costs

how much energy is needed to carry out a function

how do carbon allocation patterns change over time?

driven by sink strength, gives priority to points where resource efficiency first appears, obtains a balance between carbon fixation and nutrient water uptake, aimed at optimizing carbon gain.

cellular respiration: maintenance

replacing and repairing cells

cellular respiration: defense

chemical defense, alleopathy, structure defense

cellular respiration: construction

makes new structures, chemical reactions for growth.
