Blood vessels visible in the posterior view of the heart include the Superior and inferior vena cava and the pulmonary veins. The superior vena cava and the inferior vena cava drain systemic venous blood into the posterior wall of the right atrium. The pulmonary veins transport blood from the lungs back to the heart and are best seen in posterior view of the heart. Other features visible in the posterior view include, right and left atrium, right and left ventricle, aorta, aortic arch, pulmonary veins and arteries, coronary sinus, coronary artery and posterior interventricular artery.
Answer:
The reactants and enzymes required for a particular biological process are concentrated in a particular organelle.
Slower
Explanation:
Enzymes are usually localized in organelles to make it easier for cellular processes to occur. Enzymes are NOT randomly distributed in the cell. Each organelle is capable of a specific function and uses specific enzymes to do these processes. Enzymes are very specific and only work for certain organelles, so they are appropriately distributed throughout cells to ensure biological processes can proceed appropriately. This is also why processes would run slower if they were just in the cytoplasm, because organelles have reactant-specific enzymes to do certain biological processes, which cannot be effectively done in the cytoplasm in the cell.
