Which statement is true of carbohydrates
a carbohydrates form biological catalysts known as enzymes.
b carbohydrates carry the genetic information in plants.
c carbohydrates are major components of cell membranes.
d carbohydrates are a source of energy.

The correct answer is D carbohydrates are a source of energy .

Explanation:

Carbohydrates can be defined as Polyhydroxy Aldehydes or Polyhydroxy ketones.Carbohydrates are major source of energy in our body.

                   Carbohydrate such as glucose is broken down to through glycolysis, TCA cycle and oxidative phosphorylation collectively called aerobic respiration to generate carbon di oxide,H2O and adenosine Tri Phosphate or ATP.

            1 molecule of ATP is broken down to generate -30.5 kj/mole energy which is used as free energy by the cell to carry out various cellular and physiological process such as gluconeogenesis,Muscle contraction etc.

measuring physical properties lab reportinstructions: in the physical properties lab, you will test the physical properties of different building materials in order to pick the appropriate materials for a new home in tiny world. record your observations and test measurements in the lab report below. youwill submit your completed report.name and title: lyric lawton, mr.herbert, 10/13/17, physical properties lab. objective(s): i need to parvus build his house out of the right material, so he will stay cool in the mountains.hypothesis: if we use wood to build the roof of the house, then the temperature inside the house will remain cooler.if we use clay brick to build the walls and floors of the house, then the temperature inside the house will remain cooler.if we use aluminium to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.if we use iron to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
