"The citric acid cycle, also known as the Krebs cycle, is involved in cell respiration and produces NADH and FADH2 for the electron transport chain. The Krebs cycle also produces two ATP, but much mor ...

"In order for biological processes to proceed, organisms need to maintain standard internal balances. They do so through systems of negative feedback called homeostasis which ensure that all things ha ...
"The electron transport system is the stage in cellular respiration in which oxidative phosphorylation occurs and the bulk of the ATP is produced. The electron transport system creates an electron gra ...

"Photosynthesis is a process found in plant cells which converts light energy into chemical energy in the form of sugars that the plant can store and use at any time. Photosynthesis takes place in the ...

"Cell transport is movement of materials across cell membranes. Cell transport includes passive and active transport. Passive transport does not require energy whereas active transport requires energy ...

"Cell diffusion is a type of passive cell transport. In diffusion, molecules move from areas of high concentration to areas of low concentration in order to decrease the concentration gradient. Diffus ...

"The Calvin cycle is the second step of photosynthesis which converts ATP into glucose for storage. It is also called the "light independent reaction" or the "dark reaction" because unlike the light d ...
"Osmosis is the diffusion of water molecules across a semi-permeable membrane from an area of high concentration to an area of low concentration. In cells, osmosis occurs across the cellular membrane ...
Anaerobic respiration is the process of producing cellular energy without oxygen. Anaerobic respiration is a relatively fast reaction and produces 2 ATP, which is far fewer than aerobic respiration. A ...

"The light dependent reaction is the first step of photosynthesis which converts light energy into ATP. The light dependent reaction takes place inside the chloroplasts along the thylakoid membrane." ...
