The correct answer is: Prions are proteins that are folded incorrectly.
These misfolded proteins have abnormal 3D structure but the cause is not clearly known. They aggregate in tissue and cause it damage and cell death. Prion aggregates are stable, meaning that are resistant to denaturation by chemical and physical agents.
Prions cause neurodegenerative diseases such as Creutzfeldt–Jakob disease (fatal degenerative brain disorder) or Gerstmann–Sträussler–Scheinker syndrome (also fatal).
A triglyceride is made up of three fatty acids and one molecule of Glycerol
Answer:
Components of the electron transport chain (ordered by electronegativity from least electronegative to most electronegative):
NADH dehydrogenase >> Coenzyme Q >> Cytochrome b-c1 complex >> Cytochrome c >> Cytochrome oxidase complex > O2
Explanation:
The electron transport chain transfers electrons from donors to acceptors via redox reactions (i.e., where reduction and oxidation occur together), and couples the transfer of electrons with proton transfer (H+ ions) across the membrane. In the electron transport chain, the electrons are transferred from NADH dehydrogenase NADH to oxygen (O2) through a series of transmembrane complexes: NADH-Q oxidoreductase, Q-cytochrome c oxidoreductase and cytochrome c oxidase. In the first place, the reduced form of coenzyme Q (ubiquinone) transports the electrons from the NADH-Q oxidoreductase to the Q-cytochrome c oxidoreductase complex (Cytochrome b-c1 complex). Second, the cytochrome c transports the electrons from this complex (i.e., Cytochrome b-c1 complex) to the Cytochrome oxidase complex, this being the last component in the electron transport chain that is responsible to catalyze the reduction of O2.
Answer:
The light- independent reaction uses the energy from <u>NADPH and ATP</u> to produce <u>Sugar</u>.
Explanation:
The end product of light- independent reaction is sugar (glucose) which is made from carbon dioxide. The energy for these comes from the end results of light- dependent reactions .
This includes NADPH and ATP. This process is termed as the Calvin Cycle.
Steps of the Calvin Cycle include:
1. The formationof a six carbon sugar , Phosphoglycerate, by combination of a five carbon sugar, Ribulose biphosphate (RuBP) and Carbon dioxide.
2. The formation of two molecules of Triose Phosphate by reducing Phosphoglycerate using hydrogen atoms of the light- dependent reactions. This reaction uses ATP.
3. ATP is also used to convert some of the Triose Phosphate back to RuBP.
4. GLUCOSE is produced using the rest Triose Phosphate.
