A metabolic pathway that ___ (oxidizes or reduces) an energy-rich source to produce ATP from ADP. Electrons are transferred from

electron ___ (donors or acceptors) to compounds with a ___ (stronger or weaker) reduction potential. As electrons move through the electron transport chain, ETC, the energy in the electron is used to pump ___ across a membrane. The pumping of these molecules against their concentration gradient is a form of ___ transport. The movement of these molecules back into the cell (down their concentration gradient) releases energy which the cell couples to the formation of ___.
Photosynthesis
Energy in ___ is absorbed by an electron in a photocenter. This energy is converted from light energy into chemical energy into kenetic energy as the energized electron is used in back to back REDOX reaction in the electron transport chain, ETC. The ETC creates ___ which is used by the cell to power the formation of ATP. In ___ (cyclic or noncylcic) the electron returns to the photocenter. In ___ (cyclic or non-cyclic) photosynthesis the electron reduces NADP+ to form ___.

Answer:

Check the explanation

Explanation:

1. A metabolic pathway that OXIDIZES an energy-rich source to produce ATP from ADP.

Oxidation reactions are exergonic and can be coupled to produce ATP from ADP + Pi

2. Electrons are transferred from electron DONORS to compounds with a STRONGER reduction potential.

Electrons are moved from compounds with low reduction potential to compounds with high reduction potential.

3. As electrons move through the electron transport chain, ETC, the energy in the electron is used to pump PROTONS across a membrane.

In respiration, protons are pumped from the mitochondrial matrix to the perimitochondrial space.

4. The pumping of these molecules against their concentration gradient is a form of ACTIVE transport.

6. The energy in PHOTON/LIGHT is absorbed by an electron in a photocenter. This energy is converted from light energy into chemical energy into kinetic energy as the energized electron is used in back to back REDOX reaction in the electron transport chain, ETC.

7. The ETC creates A PROTON GRADIENT which is used by the cell to power the formation of ATP.

8. In CYCLIC ELECTRON TRANSPORT, the electron returns to the photocenter.

9. In NON-CYCLIC photosynthesis the electron reduces NADP+ to form NADPH.

Answer:

see explaination

Explanation:

1. A metabolic pathway that OXIDIZES an energy-rich source to produce ATP from ADP.

Oxidation reactions are exergonic and can be coupled to produce ATP from ADP + Pi

2. Electrons are transferred from electron DONORS to compounds with a STRONGER reduction potential.

Electrons are moved from compounds with low reduction potential to compounds with high reduction potential.

3. As electrons move through the electron transport chain, ETC, the energy in the electron is used to pump PROTONS across a membrane.

In respiration, protons are pumped from the mitochondrial matrix to the perimitochondrial space.

4. The pumping of these molecules against their concentration gradient is a form of FACILITATED transport.

Since protons are charged particles, they require a carrier protein for their transport. The movement of these molecules back into the cell (down their concentration gradient) releases energy which the cell couples to the formation of ATP.

6. The energy in PHOTON/LIGHT is absorbed by an electron in a photocenter. This energy is converted from light energy into chemical energy into kinetic energy as the energized electron is used in back to back REDOX reaction in the electron transport chain, ETC.

7. The ETC creates A PROTON GRADIENT which is used by the cell to power the formation of ATP.

8. In CYCLIC ELECTRON TRANSPORT, the electron returns to the photocenter.

9. In NON-CYCLIC photosynthesis the electron reduces NADP+ to form NADPH.

Answer:

The unit cell edge lenght in pm is equal to 361 pm

Explanation:

Data provided:

ρ=Copper density=8.96 g/cm3

Atomic mass of copper=63.54 g/mol

Atoms/cell=4 atoms (in theory)

Avogadro's number=6.02x10^{23} atoms/mol

Since copper has a cubic structure, its cell volume is equal to a^{3}, which can be obtained through the relationship:

cell volume=\frac{(atoms/cell)(atomic mass)}{(density)(Avogadros number)}

Substituting the values:

cell volume=\frac{(4 atoms)(63.54 g/mol)}{(8.96 g/cm3)(6.02x10^{23}) }=4.71x10^{-23}cm^{3}

clearing, we have:

a=\sqrt[3]{4.71x10^{-23}cm^{3}  }=3.61x10^{-8}cm

We convert from centimeter to picometer, 1cm=1x10^{10}pm

a=3.61x10^{-8}cmx\frac{1x10^{10}pm }{1cm} =361 pm
