Answer:

The steps of light reactions in order:

1. Electrons move down the electron transport chain, releasing energy

2. ATP uses energy to add a phosphate to ADP forming ATP

3. Electrons from the electron transport chain close to photosystem II replace the elctrons lost in photosystem I

4. A protein in the electron transport chain, pumps H+ ions from the stroma into the thylakoid space

5. Electrons from Photosystem I become energized and escape photosystem I and move down the second electron transport chain.

6. Water is split to replace the electrons in photosystem II

7. H+ ions flow down the concentration gradient through a channel in ATP Synthase, releasing energy in the process

8. At the end of the electron transport chain, the energized electrons and an H+ ion are used to reduce NADP+ to NADPH

9. Light energy is transferred to a chlorophyll reaction center where electrons become energized.

10. Photosystem II receives photons in the form of light energy

11. Electrons move to an electron acceptor in the electron transport chain and electrons in photosystem II are replaced by the splitting of a water molecule

I am pretty sure I got that right! :)

1. ¿Qué es la sociedad civil? ¿Quiénes la conforman? ¿Por qué es importante para la democracia?
Novay_Z [31]

Answer:

La sociedad civil también se llama tercer sector de la sociedad.

Explicación:

La sociedad civil es un tipo de sociedad que se compone de personas que exigen los derechos y deseos del público. También se le llama tercer sector de la sociedad porque es diferente del sector gubernamental y empresarial. Las personas del sector familiar y privado conforman la sociedad civil. Es importante para la democracia porque proporciona control y equilibrio sobre la democracia y evita que el gobierno tome malas decisiones.
