The term anabolism refers to those endergonic metabolic pathways involved in biosynthesis, converting simple molecular building blocks into more complex molecules, and fueled by the use of cellular energy.

However, consider endergonic reactions, which require much more energy input, because their products have more free energy than their reactants. Within the cell, where does energy to power such reactions come from? The answer lies with an energy-supplying molecule called adenosine triphosphate, or ATP.

For example, when a light bulb is turned on, some of the energy being converted from electrical energy into light energy is lost as heat energy.

It highlights mitochondrial DNA (mtDNA) mutations as a cause of diseases, influenced by heteroplasmy. Mitochondrial Replacement Techniques are being studied to prevent the transmission of defective mtDNA from mothers.

It also covers fermentation tests with yeast. Students will measure CO2 production in fermentation tubes, outline their meals with nutritional data, and calculate dietary percentages, while following cleanup instructions. Resources for food assistance, such as the Warrior Pantry and CalFresh, are also mentioned.
