... They have a prokaryotic cell structure typical of bacteria and
conduct photosynthesis directly within the cytoplasm , rather than in specialized organelles.
Eukaryotic algae
All other algae are eukaryotes and
conduct photosynthesis within membrane-bound structures (organelles) called ...

Archaea
... They also exhibit a variety of different types of metabolism. Of note, the halobacteria can use light to produce ATP , although no Archaea
conduct photosynthesis with an electron transport chain, as occurs in other groups.
Evolution and classification
Archaea are divided into two main ...
Chloroplast
... Chloroplasts are organelles found in plant cells and eukaryotic algae which
conduct photosynthesis .
Chloroplasts are similar to mitochondria but are found only in plants. Both organelles are surrounded by a double membrane with ...
Neuron
... sclerosis is a neurological disorder which results from abnormal demyelination of peripheral nerves. Neurons with demyelinated axons do not
conduct electrical signals properly.
Neurons and glia make up the two chief cell types of the central nervous system. There are far more glial cells ...
Proton pump
... ATP itself powers this transport.
The F 0 F 1 ATP synthase of mitochondria and the CF 1 ATP synthetase of chloroplasts, in contrast, usually
conduct protons from high to low concentration across the membrane while drawing energy from this flow to synthesize ATP.
Bacteriorhodopsin is a ...
Synapse
... or inhibitory in the case of hyperpolarizing currents. Whether a synapse is excitatory or inhibitory depends on what type(s) of ion channel
conduct the post-synaptic current, which in turn is a function of the type of receptors and neurotransmitter employed at the synapse.
Synaptic strength ...
Thermoregulation
