The hubble constant: measures distance using parallax angles measures the difference between absolute and apparent magnitude is a relationship between distance and velocity can only be used to measure distances of close stars

is a relationship between distance and velocity

      v = Hd, where: v = velocity of a galaxy, in km/s. H = Hubble Constant, measured in km/s/Mpc and d is the distance in km.

yes it is weird but true

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
