23
Q

One of the electron carries in the chain uses the energy released by electrons to transport ___ ions from the ____ into the space inside the ___

A

H+
Stroma
Thylakoids

24
Q

This creates a build up of h+ ions a concentration ___ of h+ across the membrane

25
The H+ ions than diffuse Through the membrane via a protein complex called ____ which captures their energy to make
Atp synthesis | Atp
26
In photosynthesis this chemiosmotic production of ATP is called
Photophosprulation
27
How does photosynthesis 2 replace its lost electrons? It gets them by splitting ___
H2O
28
When the electrons of photosystem 2 are jarred loose, the reaction center develops a strong attraction for electrons. It obtains them by breaking a molecule apart called
H2O
29
This leaves two H+ ions( which pass into the thylakoid space) and an ___. Atom
Oxygen
30
This atom combines with another from another water molecule to form a molecule of __ gas which diffuses out of the leaf- a product of photosynthesis important to us and other animals
O2
31
At this point the cells of the apple tree have cuptured the energy of the sun in molecules of NADPH and ATP, but so far they have Made no
Sugar
32
The NADPH and ATP are used, and sugar is made, in the ___ cycle the second portion of ___ that takes place in the ___ of the chloroplast around the thylakoids
Calvin Photosynthesis Stroma
33
Using carbon from ___ obtained from the air, energy from ATP and hydrogen and high energy electrons carried by __\_ the enzymes of the Calvin cycle construct ___, a high energy sugar molecule
CO2 NADH G3P
34
In a series of steps, these molecules are combined for form the important six carbon sugar ___ and other organic compounds in the leaves and other parts of the plants
Glucose
35
The cellulose that gives and apple its crunch and the sugar that gives it its sweet taste are made from the glucose made in photosynthesis. In your intestines the sugars enter your ____ and are transported to your body cells
