Hemoglobin is the oxygen-carrying protein inside red blood cells. It gives red blood cells their red color. People with anemia do not have enough hemoglobin. The body needs certain vitamins, minerals, and nutrients to make enough red blood cells. Iron, vitamin B12, and folic acid are three of the most important ones.
Which organelle would you expect to find in abundance in a muscle cell? Mitochondria because ATP is needed for muscle contraction and the mitochondria is the site of ATP production (powerhouse). Edit
Muscles work because of 2 proteins in the cells, so the muscle cells that make up your muscles contain lots of organelles that make protein. Sometimes these organelles are located on another organelle and sometimes they are found freely in the cellâs cytoplasm.
