1. True





2. True





1. Adenosine Triphosphate.





2. Membrane proteins are of two types Integral (passing through the width of the membrane (act as transport channels) and peripheral (act as recognition sites). These peripheral proteins contain carbohydrates to help in cell to cell recognition. These carbohydrates are called oligosaccharides. If they bind to proteins they become glycoproteins, if they bind to lipids, they become glycolipids. Cholesterol molecules are found in animal membranes to help add support to its structure. The majority of the phospholipids contain unsaturated fatty acids to keep it fluid.





3. Pores in the membrane.





4. Alpha and beta tubulin.





5. Inter membrane space; the area between the outer and inner membranes of t he organelles.
