Introduction to photosynthesis week 13 (DONE)

Why does each photosynthestic plant cell have many chloroplasts?

capture more light, produce more energy, and synthesize more sugar

Do the light-dependent reactions produce the oxygen (O2) molecules that enable cellular respiration in aerobic species?

Yes, produces O2 molecules which are essential for most organisms

Is your food supply directly & indirectly based on photosyntheisis?

Yes, out energy comes from if we eat both plants or animals

In algal & plant cells, the light-dependent reactions & Calvin cycle reactions occur in which organelle?

Chloroplast

In which part of this organelle do the light-dependent reactions occur?

thylakoid membranes

Which two energy rich molecules do the light dependent reactions produce?

ATP and NADPH

The Calvin cycle reactions convert the carbon dioxide (CO2) molecule into which three carbom, energy rich, carbohydrate?

glyceraldehyde 3- phosphate (G3P)

Which two, energy rich product molecules of the light dependent reaction supply the energy for the Calvin cycle enzymes?

ATP and NADPH

Which types of pigments in the pigment protein complexes capture PAR?

Chlorophyll A, chlorophyll B and carotenoids

Do plants use the 3-carbon carbohydrate, PGAL (G3P), synthesized by the Calvin cycle reactions to make all their biological molecules?

Yes,PGAL (G3p) is the central intermediate in plants, essentially for all biological molecules

Are the PGAL (G3P) molecules made by the Calvin cycle the source of your body’s biological molecules?

Yes, indirectly from photosynthesis as its the foundation of life on earth

Are the PGAL (G3P) molecules made by the calvin cycle the source of you food molecules?

Yes, directly (plants) or indirectly (animals), comes from plant G3P produced by the Calvin cycle
