In fact, every cell of your body constantly needs energy to carry out life processes. You probably know that you get energy from the food you eat, but where does food come from? How does it come to contain energy, and how do your cells get the energy from food? When you read this ...
STOMATA Stomata are located on the abaxial surface (underside) of leaves. They are part of the epidermal tissue. Carbon dioxide enters the leaf through the stomata. Water also exits the leaf through the stomata in a process called TRANSPIRATION. This helps to cool the leaf and provides a grad...
Without oxygen, the proteins in the ETC can’t pass electrons so oxygen can’t accept the electrons and therefore ATP production stops. Anaerobic environment If oxygen is not present after glycolysis, fermentation occurs to produce small amounts of ATP to keep the cell from dying. Fermentation A...
Cell respiration and photosynthesis1.Why is much needed in substrate linked reactions molecules such as NAD and FAD? 2.In the electron transport chain to what is useful that the oxygen acts as a final electron acceptor? 3.And how oxygen prevents blockages on the system? 4.What is a self ...

respiration takes place. Oxygen is used in the chemical reactions that break down the small molecules into water and carbon dioxide. • The reactions also release energy. Every cell in the organism needs this energy. The figure below shows aerobic respiration in a plant cell. Imp...

sheath cells, where the acid is decarboxylated, the CO2assimilated via the C3cycle, and the resulting three-carbon compound, pyruvic acid, moves back into the mesophyll cell and is transformed into PEP, which can be carboxylated again. The two cell types, mesophyll and bundle sheath, are not...
