The 1st Law of Thermodynamics states that

All energy on Earth initially comes from

All chemical reactions in a cell are referred to as a cell's _________

A series of reactions where the product of one reaction is the substrate for the next reaction is called a ____________

____________ reactions release energy by breaking down larger molecules into smaller molecules

____________ reactions use the energy released by catabolic pathways to build larger molecules from smaller molecules

__________ the anabolic pathway in which light energy from the Sun is converted to chemical energy for use by the cell.

__________ the catabolic pathway in which organic molecules are broken down to release energy for use by the cell

This process occurs in the Chloroplast.

This process occurs in the Mitochondria.

6CO₂ + 6H₂O + Energy → C₆H₁₂O₆ + 6O₂

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy

A set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into ATP (energy), and then release waste products.

The process of producing cellular energy without oxygen. A relatively fast reaction and produces very little energy.

Anaerobic respiration takes place in the _________

A type of anaerobic respiration that takes place in humans is called ____________

The most important biological molecule that provides chemical energy is

Due to ATP having a nitrogen base, ribose sugar, and phosphate groups it is classified as which macromolecule?

The energy from ATP comes from ________ bonds between phosphate groups.
