Summary Introduction

To analyze:

The kilocaloric input and output adjusted to maintain body weight.

Introduction:

The metabolic rate is the maximum amount of energy that the body produces and consumes per unit of time. A molecule of ATP exists for less than 1minute before it is degraded back to ADP and inorganic phosphate. For this reason, ATP is produced in cells at about the same rate as it is used. Thus, in examining metabolic rate, ATP production and use can be roughly equated. Because most ATP production involves the use of O₂, metabolic rate is usually estimated by measuring the amount of oxygen used per minute.
