The mitochondrial structures are the site of the enzymes and carriers used to make ATP in the electron transport system are CRISTAE. These membrane structures form mitochondria.
<h3>Mitochondria and cellular respiration</h3>
Cellular respiration refers to the metabolic reaction by which aerobic cells produce ATP by using the energy stored in the chemical bonds of foods.
The Krebs cycle and oxidative phosphorylation are steps in cellular respiration that occur in the mitochondria.
A crista or cristae (plural) refers to a fold in the inner membrane of mitochondria, which is required during cellular respiration.
Plants need water and sun to create their food source, glucose. When the plant was left in the closet it didn't have access to the sun. One of the requirements of life is that all living things need energy/have a metabolism. Without food the plant eventually died.
