Positive impacts of genetic engineering:
• New products are created such as food with higher nutrition values, drugs that are more effective and safer
• Disease prevention (“correcting” the genetic mutation, or removing disease-causing gene)
Negative impacts of genetic engineering:
• irreversible side effects, for example resistance of bacteria or introduction of viruses in human cells
• abusing like change specific traits that are not connected with diseases, create human outcomes that are ethically questionable.

A primary role for the glucose molecule is to act as a source of energy; a fuel. Plants and animals use glucose as a soluble, easily distributed form of chemical energy which can be 'burnt' in the cytoplasm and mitochondria to release carbon dioxide, water and energy.
