14. Which of the following occurs during the electron transport chain? a. the formation of ATP by oxidative phosphorylation
b. the formation of water
c. a concentration gradient of protons
d. all of the above

All

Explanation:

The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

D

Explanation:

ATP is created in the ETC

Water is formed as a by product

The concentration gradient is what fuels the ETC. Protons (H+ ions) move across the membrane to create energy.

Hope that helps (and also hope its right, i did bio a while back)

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

i think the answer is gold im not entirely sure
