What is the role of ATP when large molecules need to be transported across the cell membrane against the concentration gradient?
Anon25 [30]

Answer:

b. the bond between the phosphate groups is broken to release energy

Explanation:

  • Phosphate groups are negatively charged => there is a pull between the two groups

=> it's easy to break this bond & ATP is unstable

=> ATP has a lot of free energy

  • breaking the bond between phosphate groups makes the molecules more stable (aka contains less free energy)

=> delta G <0

=> breaking this bond releases energy

  • the energy released by ATP is then used to transport large molecules against the concentration gradient

How do the properties of water allow it to be transported from the roots to leaves?
Flauer [41]

Answer:

Water has the property of cohesion and adhesion. Cohesion provides the property of water to get attached with other water molecules and it holds water molecules together, adherence provides the property of stickiness to any surface to the water molecule.

These two properties together allow water molecules to move upwards against gravity. Water moves by capillary action through the water column. Cohesion and adhesion create a pull on the column which transport the water towards the leaves from where they get evaporated.  

This evaporation then causes tension on another water molecule and this tension then pulls another water molecule towards leaves.
