Sequence for the movement of electrons during the light dependent reaction
Explanation:
1.These reactions occur within specialised membrane discs within the chloroplast called thylakoids and involve three steps: Excitation of photosystems by light energy. Production of ATP via an electron transport chain. Reduction of NADP+ and the photolysis of water.
2.The cyclic light-dependent reactions occur only when the sole photosystem being used is photosystem I. Photosystem I excites electrons which then cycle from the transport protein, ferredoxin (Fd), to the cytochrome complex, b6f, to another transport protein, plastocyanin (Pc), and back to photosystem
3.Light-dependent reaction. In photosynthesis, the light-dependent reaction uses light energy from the sun to split water (photolysis). ... Water, when broken, makes oxygen, hydrogen, and electrons. These electrons move through structures in chloroplasts and by chemiosmosis, make ATP
4.The two products of the light-dependent reactions of photosystem are ATP and NADPH. The movement of high energy electrons releases the free energy that is needed to produce these molecules. The ATP and NADPH are used in the light-independent reactions to make sugar.
Answer:
An intermediate is a species which appears in the mechanism of a reaction, but not in the overall balanced equation. Examples: Amphibian/land vertebrate (Pederpes)- Intermediate form between primary aquatic Upper Devonian amphibians and early tetrapods. Lizard/snake (Pachyrhachis)—Intermediate form of snakes and an extinct lizard-like reptile. It was a primitive snake with limbs.
Explanation:
Answer:
Mississippian fossils are abundant in portions of the Midwest and South and include vast beds of limestone and marble.
Explanation:
For example, the domed ceiling of the Jefferson Memorial in Washington, D.C., is made of Indiana limestone that was deposited during the Mississippian Period.By the end of the Carboniferous, reptiles had migrated well toward the interior of Pangea. These early pioneers went on to spawn the archosaurs, pelycosaurs, and therapsids of the ensuing Permian period. (It was the archosaurs that went on to spawn the first dinosaurs nearly a hundred million years later.)
