Respiration is a process where many chemical bonds inside the body break and release energy. This energy is used to perform various activities such as moving muscles. Explain the energy transformation in this process.
О
А.
Chemical energy from broken bonds is transformed into mechanical energy for muscles.
B. Mechanical energy from broken bonds is transformed into chemical energy for muscles.
C. Mechanical energy from broken bonds is transformed into electrical energy for muscles.
D
Heat energy from broken bonds is transformed into electrical energy for muscles.

Describe the iron sulfide hypothesis and the lipid membrane hypothesis.

Match the following terms describing electrical events with the correct phases of the cardiac cycle. the ventricular muscle cells depolarize at the start of this phase. during this phase, na+ entry through the funny channels causes the pacemaker potential of sa nodal cells to gradually become less negative until it reaches threshold. the ventricular muscle cells repolarize right before this phase. the cytosolic concentration of calcium in the contractile cells of the ventricle is highest during this phase. a. isovolumetric relaxation b. ventricular ejection c. isovolumetric contraction d. ventricular filling

The pattern of this wave changes between its beginning and end. what is true about the amplitude and wavelength of the wave when the pattern changes?
