I need help with my science question Which molecules do cells need to release energy? Here is the choices. Claim 1: Cells need glucose to release energy. Claim 2: Cells need amino acids to release energy. Claim 3: Cells need oxygen to release energy. Claim 4: Cells need glucose AND amino acids to release energy. Claim 5: Cells need glucose AND oxygen to release energy Claim 6: ALL?

The statement 'cells need glucose AND oxygen to release energy' is correct (Claim 5).

Cellular respiration is a series of metabolic reactions by which aerobic cells used oxygen and the energy stored in the chemical bonds of foods (e.g., glucose) to produce ATP.

Cellular respiration has three main stages: glycolysis, the citric acid cycle and oxidative phosphorylation.

During glycolysis, a molecule of glucose is used to create two molecules of pyruvate, which enter into the citric acid cycle.

Oxygen is the last acceptor of electrons in the electron transport chain of oxidative phosphorylation.

In conclusion, cells need glucose AND oxygen to release energy.

Claim 5: Cells need glucose AND oxygen to release energy.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage through the breathing of oxygen used to obtain energy from the food ingested.

Hence, cells need glucose and oxygen to release energy.
