Answer:
Embryonic stem cells have a larger differentiation potential than adult stem cells
Explanation:
This is because embryonic stem cells can develop in any other type of differentiated cell type in the body (pluripotent), while adult stem cells are limited in that way (multipotent or unipotent). So, we can say that embryonic stem cells are more flexibile.
Another advantage of the embryonic stem cells is that they are more easily grown in culture.
Embryonic stem cells- derived during early development
Adult stem cells-derived from adult tissue

Explanation:
The process of cellular respiration, which generally involves the synthesis of energy from carbohydrate molecule (glucose), occurs in four major steps in eukaryotic cells. These steps are glycolysis, kreb cycle, bridge or intermediate step and oxidative phosphorylation (electron transport chain).
The features of each step is highlighted below:
GLYCOLYSIS: This is the first stage if cellular respiration in which Glucose is broken down into 2 pyruvic acid (pyruvate). It can occur without oxygen in the system and it uses 2 ATP molecules to start the process.
INTERMEDIATE STAGE: This stage is also called bridge or transition reaction. It does not produce any ATP molecule but only prepares the reaction for aerobic respiration in the mitochondria by turning Pyruvate molecule into acetyl CoA.
KREB'S CYCLE: This is the third step in the process. AcetylcoA undergoes series of chemical processes to release 4 carbon dioxide molecules and generates FADH2 and NADH electron carriers. It takes two cycles to process two glucose molecules that is used in the respiration process.
ELECTRON TRANSPORT CHAIN: In this stage, approximately 34 ATP molecules are produced in the mitochondria using enzyme called ATP synthase, which catalyse the conversion of ADP to ATP.
ANAEROBIC RESPIRATION: This type of respiration occurs in the absence of oxygen. In animal cells, lactic acid/lactate is produced and stored in the muscle as an end product
