The energy required for the mechanism of "active transport" comes from: 1.the reactants which yield atp 2. the product of atp decomposition 3. photosynthesis 4. cytokinesis

2. the product of ATP decomposition

Explanation:

The Adenosine  triphospahte ATP is an energy currency made up,of 3 phospahte ions bonded to adenosine molecule

Each of these inorganic ions is  bonded to Adenosine molecule by certain bond energy.Therefore the hydrolysis of these phosphate ions release equal amount of  ENERGY  of value

ATP HYDROLYSIS  ADP + P(ions)

(30,5kj/mol) of energy  for the first 2 inorganic phosphate hydrolysed, and 14.2kjmol for the  last inorganic phosphate.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
