In a metabolic experiment a 229 gm rat consumed 30 ml of oxygen in 7 min. Calculate the oxygen consumption per hour. Calculate the metabolic rate in ml O2/Kg/hr.

Solutions

Expert Solution

oxygen consumption per hour equation is

ml oxygen consumed / 1 minute × 60 minutes/ hour = ml oxygen per hour

oxygen consumed = 30ml in 7 minutes

rat weight = 229 grams

rat consumed oxygen 30ml in 7 minutes

per 1 minute = oxygen consumption is

oxygen consumed = 30/7 = 4.28 ml of oxygen consumed per 1 minute...

  oxygen consumption per hour is

= 4.28ml of oxygen per  1 minute × 60 minutes/hour

= 256.8 ml of oxygen per hour

oxygen consumption per hour is = 256.8 ml / hour

metabolic rate of oxygen in ml / hour/ kg

metabolic rate equation is

(ml of oxygen/ hr) × (weight in kg) = ml of oxygen/hr/ kg

from above ml of oxygen per hour is =256.8 ml/ hour

rat weight is 229 gms is converted into kg

229 gms = 0.229 kg

metabolic rate = 256.8 ml/ hr  × 0.229 kg

= 58.80 ml of oxygen/ hour/ kg

answer:

metabolic rate = 58.80 ml of oxygen/hr/kg

oxygen consumpconsumer hour = 256.8 ml/ hour
