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
The muscle cells are wrapped by fibroconnective tissue which maintains the shape of the muscle, and carries the blood vessels and nerves to the muscle tissue. The muscle cells themselves are elongate, and are often referred to as muscle fibers. These contain the intracellular contractile elements, the myofilaments.The intracellular organization of these elements is greatest in skeletal muscle and least in smooth muscle. The three types of muscle are described in more detail below.he muscle cells themselves are elongate, and are often referred to as muscle fibers. These contain the intracellular contractile elements, the myofilaments. The intracellular organization of these elements is greatest in skeletal muscle and least in smooth muscle.
