Here's why:
* Cellular Respiration: This is a fundamental metabolic process that occurs in the cells of all living organisms. It breaks down glucose (a sugar) in the presence of oxygen to produce energy in the form of ATP (adenosine triphosphate). This energy is used to power various cellular activities.
* Heterozygosity: This refers to having two different alleles (versions) of a gene. It doesn't impact the fundamental energy-releasing process of cellular respiration.
Important Note: The genotype of an organism (whether heterozygous or homozygous) doesn't change how it performs basic cellular processes like respiration. It's the specific alleles and their interactions that might affect traits related to metabolism, but not the fundamental process of energy release itself.
