Answer:
In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis. In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy "powerhouses" of the cells 
 
        
             
        
        
        
The correct answer is (b.) euglenophytes. Phosphorescence is a phenomenon associated with an algal division called euglenophytes. Euglenoids are one of the most known flagellates which are excavated eukaryotes of the phylum euglenophyte. Euglenophytes are single-celled plant-like protists that have no cell wall.

Answer: CHANNEL PROTEINS provide openings in the plasma membrane for substances to flow through without changing structure, and CARRIER PROTEINS allow passage of substances through the plasma membrane after undergoing a subtle change in shape.
Explanation: They are described thus:
A channel protein is a protein that allows the transport of specific substances across a cell membrane.
Carrier proteins are proteins that carry substances from one side of a biological membrane to the other. Many carrier proteins are found in a cell’s membrane, though they may also be found in the membranes of internal organelles such as the mitochondria, chloroplasts, nucleolus, and others.
