In the mitochondria
Not always. When they don't they die.
through carbohydrate containing foods
Animals and humans eat food to stay alive. Metabolic processes break down the food (plants and animals) to obtain energy, and the materials needed to build and repair the body.
Most animals produce carbon dioxide through a process called cellular respiration. During this process, cells break down glucose to obtain energy, releasing carbon dioxide as a byproduct. The carbon dioxide is then expelled from the body through respiration or other methods like diffusion in aquatic animals.
cellular respiration.
All cells obtain energy from cellular respiration. Some undergo anaerobic respiration and some undergo aerobic respiration.
During cellular respiration, animals primarily take in oxygen and glucose. Oxygen is essential for the process of aerobic respiration, allowing cells to produce energy, while glucose serves as the main source of chemical energy derived from the food they consume. Together, these materials enable cells to generate ATP, the energy currency of the cell.
Animals, fungi, and most bacteria are examples of organisms that use cellular respiration but do not perform photosynthesis. These organisms obtain energy by breaking down organic molecules like glucose to produce ATP through cellular respiration.
They conduct only respiration. Animals are not photosynthetic.
Animals obtain the materials needed for respiration by either breathing in oxygen from the air or absorbing oxygen from water. In the process of respiration, oxygen is used to break down glucose to produce energy, and carbon dioxide is released as a waste product.
In Cellular Respiration, we get energy from the plants and animals we consume. So we indirectly obtain energy from the sun.
