Unlike skeletal muscle, the muscle cells of the heart (called "cardiomyocytes") metabolize very little glucose, relying almost exclusively on metabolism of fatty acids for their energy. which of the following statements are likely to be true of cardiomyocytes, but not skeletal myocytes? (select two answers) low levels of glycogen storage, even when blood glucose is high high levels of glycogen storage, even when blood glucose is lovw o low lactate production, even at high activity high lactate production, even at low activity many mitochondria compared to other cells few mitochondria compared to other cells

Which is an advantage of having memory cells when a pathogen is encountered for a second time. a) the memory cells are what proliferate into clones of cells in response to the binding of an antigen. b) memory cells are vital to the primary immune response in that they immediately recognize pathogens even at the first encounter. c) memory cells are essentially effector cells that are short lived and attack antigens even without having a receptor specific to that antigen. d) it ensures that more lymphocytes with a receptor specific to a particular antigen will be present than in a host that had never encountered that pathogen.
