I'm not sure if this is correct, but the answer I got was: endoplasmic reticulum.
I hope this helps, and have a good night! :D
        
                    
             
        
        
        
Lysozyme which is found in the lysosomes. They function at a relatively low pH and are so because if they functioned at physiological pH they would digest the cell. But in this case, they are in the lysosomes where they are safe and at a lower pH so when the vesicles open they can emit hydrogen ions and the lysozyme to digest the foreign material.
        
             
        
        
        
Answer:
One.
Explanation:
The attached figure shows the diagram of the given question. 
We need to find how many angles are alternate exterior angles with angle 5?
Exterior angle = Angle that is made outside of the shape
Alternate angle = an angle opposite of a transversal line of another angle.
From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.
