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
Answer:
endosymbiosis.
Explanation:
By the beginning of the 20th century, researchers thought that plastids and mitochondria could come from bacteria. These would have been ingested by primitive cells and live within them in symbiosis.
