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
1 In muscle cells, actin filaments are aligned and myosin proteins generate forces on the filaments to support muscle contraction. 2  In non-muscle cells, actin filaments form a track system for cargo transport that is powered by non-conventional myosins such as myosin V and VI. Microfilaments provide cell motility. 2  e.g., Filopodia, Lamellipodia. 3  During mitosis, intracellular organelles are transported by motor proteins to the daughter cells along actin cables. 4  In muscle cells, actin filaments are aligned and myosin proteins generate forces on the filaments to support muscle contraction.
