Answer:
four oxygen molecules
Explanation:
The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.
Cellular respiration
Explanation:
The energy animals need for their life functions are released when their cells carry out cellular respiration.
Cellular respiration is a metabolic process by which living organisms breaks down organic molecules using oxygen especially glucose to produce energy and gives off carbon dioxide and water in the process.
It is the reverse of photosynthesis.
During this process, chemical energy stored in food substances are released and converted to heat energy.
The process takes place in the mitochondria of a cell.

Answer:
The (rough) endoplasmic reticulum
Explanation:
The endoplasmic reticulum is a system of interconnected membranes that functions in the synthesis of several membrane-related proteins and lipids. There are two types of endoplasmic reticulum in the eukaryotic cell;
- Smooth endoplasmic reticulum
- Rough endoplasmic reticulum
The smooth endoplasmic reticulum is actually smooth because it has no ribosome attachment while the rough endoplasmic reticulum appears rough due to the attachment by ribosomes.
<em>Therefore, the name of the specific organelle that is studded with ribosomes in eukaryotic cell is endoplasmic reticulum.</em>
