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.

Atoms of iron (fe) and sulfur (s) form iron sulfide (fes) when the iron atom donates electrons to the sulfur atom. the type of b
marysya [2.9K]

Answer:

               The type of bond formed in FeS would be <u>Polar Covalent Bond</u>.

Explanation:

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

               Less than 0.4 then it is Non Polar Covalent  Bond

               Between 0.4 and 1.7 then it is Polar Covalent  Bond

               Greater than 1.7 then it is Ionic  Bond

For Fe and S,

                   E.N of Sulfur           =   2.58

                   E.N of Iron              =   1.83

                                                  ________

                   E.N Difference            0.75          (Polar Covalent Bond)

Can someone help please!!!!​
Valentin [98]

2. 5 acids: coffee, lemonade, soda pop, orange juice, vinegar

5bases: ammonia, baking soda, cough medicine, liquid soaps

3. Acids are very common in some of the foods we eat.

Bases have properties that mostly contrast with those acids

4. Acid+Base=H2O+Salt

HCI+NaOH=H2O+NaCI

Explanation:

2. (all those acids are strong (in pH meaning those are weak and don't affect you) (most the bases are very strong like ammonia)

4. Salt means any ionic compound formed from an acid/base reaction

Hope this helped

How many grams are in 1.6 moles of potassium bromide?​
slava [35]

Answer:

190.4g

Explanation:

1.6mol of KBr (119.002g KBr/1 mol) = 190.4g

since you want to find grams, take the molar mass of KBr (119.002) per 1 mol and use it as your conversion factor (119.002g KBr/1 mol) which will then cancel out mols and leave you with grams.
