Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which best describes how organisms obtain energy from food?
A
Food (Glucose) reacts with water to release energy during photosynthesis.
B
Food (Glucose) reacts with oxygen to release energy (ATP) during cellular respiration.
C
Food (Glucose) reacts with sunlight to release energy during photosynthesis.
D
Food (Glucose) reacts with carbon dioxide to release energy during cellular respiration.
Explanation: 

Detailed explanation-1: -Cellular respiration is the process by which the energy in food is converted into energy that can be used by the body’s cells. The energy stored in glucose is transferred to ATP. The process can be summarized as: glucose + oxygen carbon dioxide + water.

Detailed explanation-2: -Plants get the energy they need for photosynthesis from sunlight. Which best describes how organisms obtain energy from food? Food reacts with oxygen to release energy.

Detailed explanation-3: -Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists.

Detailed explanation-4: -Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP . Generally speaking, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.

Detailed explanation-5: -Once glucose is digested and transported to your cells, a process called cellular respiration releases the stored energy and converts it to energy that your cells can use. Cellular respiration consists of three metabolic processes: glycolysis, the Krebs cycle, and oxidative phosphorylation.
