Question 12 1 pts What is not an important use that plants have, for the nutrient nitrogen? Plant cell walls are rich in nitrogen, because cellulose contains many nitrogen atoms Nitrogen is in every amino acid, and therefore is in every protein Phospholipids, such as phosphatidyl ethanolamine, contain nitrogen as part of their polar head groups ATP contains several nitrogen atoms Plants need nitrogen as part of every new DNA molecule that they make

Match the functions listed on the left to the subcellular organelles responsible for those functions listed on the right. Question 6 options: 12345678910 sub-cellular organellse actually responsible for the packaging of cellular proteins that must be contained within membrane-bound vesicle. Proteins 'packaged' by these organelles would include hydrolytic digestive enzymes that are used within the cell but must be sequestered away from other parts of the cell so they don't digest the cell itself, or enzymes like catalases and dismutases...

The inner membrane divides the mitochondrion into two internal compartments. The first compartment is the and outer membranes. The inner membrane encloses the mitochondrial mitochondrial DNA, ribosomes, and enzymes. Some of the metabolic steps of cellular respiration are catalyzed by enzymes in the matrix. Other proteins that function in respiration, including the enzyme that makes ATP, are built into the inner membrane. The highly folded cristae present a region between the inner space, a narrow a fluid-filled space with surface...
