Cell respiration

1. The first step in cellular respiration and occurs in the cytoplasm of the cell
3. This process occurs over a complex metabolic pathway involving multiple enzymes and paired reactions.
4. The phosphate group is removed from an intermediate reactant in the metabolic pathway
7. Flavin adenine dinucleotide reduced
8. Also called the tricarboxylic acid (TCA) cycle or citric acid cycle. It is the continuation of aerobic cellular respiration after glycolysis, and it takes place in the mitochondrial matrix.
10. cellular respiration generates ATP when insufficient oxygen is available for aerobic respiration.
11. Is the movement of ions across a selectively permeable membrane down an electrochemical gradients.
12. Are molecules capable of accepting electrons from one molecule and donating them to another via the process of electron transport.
13. The potential energy from these gradients is often used to perform biological processes by chemiosmosis.
15. Lactic acid can rise to harmful levels, causing symptoms such as nausea, abdominal pain, weakness or irregular heart rhythm.
17. The process by which animals convert food into a type of energy usable by their cells

1. The 6-carbon glucose molecule is split into two 3-carbon pyruvate molecules, producing only a small amount of energy
2. The most common fermentation process carried out by animals. In this process, the organic molecule acting as the electron acceptor is pyruvate.
5. It refers to all reactions that involve the transport of electrons from an electron donor to an electron acceptor.
6. Is the movement of ions across a selectively permeable membrane down an electrochemical gradients.
9. defined as the difference in charge and chemical concentration across a membrane
10. A complex transmembrane protein that utilizes potential energy stored via the electrochemical gradient to synthesize ATP
14. Break down larger complex molecules into smaller molecules.
16. When oxygen is present...cellular respiration takes place.
