LIGHT & PIGMENTS
This color of light penetrates deepest in seawater.
What is blue light?
Nearly all marine producers use this process to fix carbon.
What is photosynthesis?
The light-dependent stage occurs in these membranes of the grana.
What are thylakoid membranes?
Carbon fixation using chemical energy instead of light.
What is chemosynthesis?
This type of respiration uses oxygen.
What is aerobic respiration?
This color of light is absorbed quickly and only reaches shallow water.
What is red light?
In the word equation for photosynthesis, these are the two products.
What are glucose and oxygen?
The Calvin cycle occurs in this part of the chloroplast.
What is the stroma?
These deep-sea habitats are classic sites of chemosynthetic food webs.
What are hydrothermal vents?
These are the waste products of aerobic respiration.
What are carbon dioxide and water?
This term means the depth to which light can pass through water.
What is penetration?
This molecule is split during photolysis.
What is water?
These are stacks of thylakoids.
What are grana?
This dissolved substance is the key energy source used by Endoriftia in the notes.
What is hydrogen sulfide?
This type of respiration yields only about 2 ATP per glucose.
What is anaerobic respiration?
This primary pigment in photosystems absorbs blue and red light.
What is chlorophyll a?
These two molecules made in the light-dependent stage are passed to the Calvin cycle.
What are ATP and reduced NADP?
This enzyme combines CO2 with RuBP during carbon fixation.
What is rubisco?
These bacteria live inside Riftia’s trophosome.
What is Endoriftia?
More active fishes have more of these organelles to produce large amounts of ATP.
What are mitochondria?
These pigments broaden the range of wavelengths absorbed and help producers survive deeper down.
What are accessory pigments?
This process links light capture to food-web productivity.
What is photosynthesis?
This 5-carbon molecule combines with carbon dioxide in the Calvin cycle.
What is RuBP?
This Riftia structure acts like external gills and absorbs materials for its symbionts.
What is the plume?
If cells are using ATP quickly, they must do this at a fast rate to replace it.
What is respire (undergo respiration more...) rapidly?
