The energy for ATP synthesis comes from organic molecules (such as carbohydrates), or from sunlight, or from inorganic electron donors. We can classify organisms according to their source of energy and organic carbon:
<span><span>heterotrophs – get energy and organic carbon from metabolism of pre-existing organic compounds (food)</span><span>photoautotrophs – use energy from sunlight to make ATP and their own organic carbon compounds from carbon dioxide chemoautotrophs</span><span> – use energy from inorganic chemicals to make ATP and their own organic carbon compounds from carbon dioxide</span></span>
Metabolic pathways carry out reactions that capture energy from these various sources (organic compounds, sunlight or chemicals) and couple them to synthesis of ATP from ADP.
Answer:
answer is 1
it would have no food.
Explanation:
Photosynthesis also uses carbon dioxide faster than respiration produces it. Oxygen surplus is released into the air and unused glucose stored in the plant for later use. This is why plants are so important to human and other animals' survival. Without photosynthesis, we wouldn't have oxygen or food to stay alive.
Plant cells respire, just as animal cells do. If they stop respiring, they will die. Remember that respiration is not the same as breathing, so take care - plants do not breathe.
Answer;
-Starch, moderately branched
-Starch is a polysaccharide that is found primarily in plant cells as a form of energy storage. it is moderately branched and as a result, it is not very soluble in water.
Explanation;
-Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Starch is among the three important polysaccharides that are composed of glucose, others being, glycogen, and cellulose, are composed of glucose.
-Starch and glycogen serve as short-term energy stores in plants and animals, respectively. The glucose monomers are linked by α glycosidic bonds.
-Glycogen and starch are highly branched, which is an advantage in that the enzymes that build up and break down glycogen and starch act on the free ends of the polysaccharides. The branching thus ensures that plants and animals can quickly add to their energy supply when energy is plentiful, or break it down the storage molecules when energy is in short supply.
