Answer:
Proteins/fats
Explanation:
Which of the following classes of molecules produces the most energy per gram?
There are four classes of biological molecules: fats, carbohydrates, proteins, and nucleic acids. Of these, fats produce the most energy per gram at a whopping nine calories per gram.
Answer:
Water
Explanation:
Molecular oxygen is the terminal electron acceptor and serves to receive electrons from reduced NADH and FADH2 to reoxidize them. NADH and FADH2 are formed during glycolysis and Kreb's cycle. These reducing powers should be re-oxidized to enter in the first two steps of aerobic respiration again.
For the purpose, NADH, and FADH2 transfer their electrons to the molecular oxygen via electron transport chain. After accepting the electrons, molecular oxygen is oxidized into the water molecule. Therefore, radioactive oxygen isotope would appear in the form of a water molecule after completion of cellular respiration.
Answer:
By squeezing a bulb attached to the wide end of the pipette
Explanation:
You squeeze the bulb and place it on the wide end of the pipet. Then you place the tip of the pipet in the solution and release your grip to pull it into the pipet.
B is wrong, unless you want to accidentally get a mouthful of the sulfuric acid or cyanide you are pipetting.
C and D are wrong. Even the wide end of a pipette is too narrow to fill with either a beaker or an eyedropper.
Answer:
<u>Option-(B): </u>The activation of a plasma membrane voltage gated sodium ion channel, leads to the process involving reverse calmodulin activity inside the muscles cells.
- As, the required number of energy is required for each break to bind the different proteins and other elements with one another in a proper sequence in order to have the activities inside the body.While, the enormous number of cross bridges are there inside the muscle cells to enhance its abilities to attain a proper position inside the space for a having the different chemicals in a more balanced level.
- As, we have heard of the balance been created between the different inside the human body to attain equilibrium, which is all due to termination of a certain process while initiation of another in the same space or system.
