Tanzania [10]3 years ago
6 0

The 3 checkpoints include G1 where the cell growth is checked, G2 where the integrity of the DNA/chromosome is checked, and M where the integrity of the metaphase plate is checked.

<h3>Cell cycle checkpoints</h3>

There are 3 regulatory checkpoints in the life cycle of cells:

  • G1: the size of the cell, the presence of growth factors, and the integrity of the DNA are checked before the cell irreversibly commits to division.
  • G2: the integrity of the DNA and the correctness of the replication process at the S-phase are checked.
  • M: correct attachment of the spindle fibers to the chromosomes at the metaphase plate is checked.

Which of the following is true of anabolic reactions? View Available Hint(s) Which of the following is true of anabolic reaction
puteri [66]

Answer:

Anabolic reactions use ATP and small substrates as building blocks to synthesize larger molecules.

Explanation:

Anabolic reactions are part of metabolic pathways that occur inside the living cells. Anabolic reactions always form complex molecules from simpler substances. The formation of glucose from relatively simpler CO2 and H2O during the Calvin cycle is an example of the anabolic pathway. During anabolic pathways, the metabolic energy of ATP hydrolysis drives the endergonic reactions. Therefore, anabolic reactions consume ATP. Calvin cycle uses the ATP produced during light reactions of photosynthesis.
