First answer is A
Second answer is C
In photosynthesis, the movement of protons from the stroma to the thylakoid lumen is proton gradient and is coupled to<u> transfer of </u><u>protons</u>.
Protons are transported across the thylakoid membrane and into the lumen through the electron transport chain (the space inside the thylakoid disk). Protons are simultaneously removed from the stroma by reduction of NADPH and added to the lumen via water splitting (the space outside the thylakoids). Protons are pumped from the stroma to the thylakoid lumen as a result of the electron passing through the first link in the electron transport chain. A fourth protein complex in the thylakoid membrane, ATP synthase, then uses the energy stored in this proton gradient to produce ATP. This protein complex, like the mitochondrial enzyme, links proton flow back across the membrane to the creation of ATP.

Answer:
Surface area of the cube = 6cm²
Volume of the cube = 1cm³
Explanation:
The surface area of a cube, which refers to the sum of all the areas of the faces of the cube can be calculated using the formula:
S.A = 6 × a²
That is; a² + a² + a² + a² + a² + a²
Where;
a = length of a side of a cube
a² = area of one side of a cube
Note that, a cube has 6 faces
According to this question, a cube has a length of 1cm on each side.
Hence, S.A = 6 × 1²
S.A = 6 × 1
S.A = 6cm²
Volume of the cube can be calculated using the formula: a³
Where a = 1
Volume = 1 × 1 × 1
Volume = 1cm³
