Question

mitochondria are known as the powerhouses of the cell. they are organelles that act like a digestive system that takes in nutrients, breaks them down, and creates energy for the cell. the process of creating cell energy is known as cellular respiration. most of the chemical reactions involved in cellular respiration happen in the mitochondria. a mitochondrion is shaped perfectly to maximize its efforts.

1. what process happens in the mitochondria?
2. what is the purpose of the process in #1?

introduction to cellular respiration
organisms, such as plants and algae, can trap the energy in sunlight through photosynthesis and store it in the chemical bonds of carbohydrate molecules. the principal carbohydrate formed through photosynthesis is glucose. other types of organisms, such as animals, fungi, protozoa, and a large portion of the bacteria, are unable to perform this process. therefore, these organisms must rely on the carbohydrates formed in plants to obtain the energy necessary for their metabolic processes. this means they must eat plants and other animals in order to gain energy.

1. some organisms perform photosynthesis to produce energy. other organisms cannot do photosynthesis. what can they do in order to generate energy?

Explanation:

1. As stated in the text, "Most of the chemical reactions involved in cellular respiration happen in the mitochondria."
2. The text mentions that mitochondria "take in nutrients, break them down, and create energy for the cell" and the process is cellular respiration.
3. The text says, "These organisms must rely on the carbohydrates formed in plants to obtain the energy necessary for their metabolic processes. This means they must eat plants and other animals in order to gain energy."

Answer:

1. Cellular respiration
2. To create energy for the cell
3. They must eat plants and other animals.
