What molecule can mix with water and it also a source of energy and a storage area?

2 answers:

4 0

Answer:Lipids are organic molecules which can be used for long-term energy. These includes fats, waxes, sterols, glycerides, phospholipids, etc. Lipids contain more energy per unit mass which makes it much lighter. However, their insolubility to water makes them harder to transport.

katovenus [111]

The another are differentiated from the anamniotes by the presence of their terrestrially adapted eggs. These eggs are protected by amniotic membranes. Development of these membranes have provided another with their own aquatic environment needed for development.

The development of amniotic membrane is a characteric of amniotic eggs. These membranes include: chorion' facilitating the exchange of gases between the embryo and the mother; amnion, protection the embryo from injuries and shock and also aiding hydration; allantois, excretion of nitrogenous waste such as urea and uric acid etc and also help in respiration.

Another characteristics is waterproof skin due to the presence of lipids.

Another is the existence of costal rib ventilation of the lungs: enables of loss of CO2 through the lungs rather than buccal pumping as foumd in anamniotes.

Stels [109]

Explanation:

<u>A.light intensity</u>

<u />

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen

At the compensation point, the rate of CO2 production by respiration matches the rate of CO2 utilization in photosynthesis- there is no net CO2 production . Since photosynthesis is rate limited, the rate of energy intake can be reduced in order to reach the compensation point; lowering the light intensity would slow the rate of photolysis and thus photosynthesis. Similarly, an increase in light intensity

increases the rate of photosynthesis- the CO2 level would be reduced as more inorganic CO2 is fixed, together with producing O2 as waste.
would increase the temperature of the environment- light energy is converted to heat energy which increases temperature.
lead to higher levels of humidity- the heightened temperature increases the rate of evaporation of water from tissues, and thus increases the humidity (water vapor content of the surrounding air)

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.
