Answer:
It requires energy
Explanation:
In the coupled transport system, coupled carriers couple the inward transport of one solute across the membrane to the outward transport of other solutes across the membrane. The tight bonding that occurs between the transport of two solutes allows these carriers to utilize the energy stored in one solute, usually an ion, to facilitate transport of the other. With this way, the free energy released during the movement of an ion down an electrochemical gradient is utilized as the driving force to transport other solutes inwards, against their electrochemical gradient.
Answer:
a. No, because Acetyl CoA goes into the TCA cycle, which will not occur in cells without oxygen.
Explanation:
Fatty acids in the body gets converted to acetyl-CoA by the process of β-oxidation. After the conversion of fatty acids to acetyl-CoA , acetyl-CoA undergoes the TCA cycle which produces NADH and FADH₂ which further undergoes electron transport chain where oxygen gas acts as the final receptor for these molecules and high energy molecules known as ATP are released in the process.
<u>Thus, in the absence of oxygen, TCA will not occur and thus no energy is provided to the body.</u>
The pumping of the heart is tied to the respiratory system
C.) NaCl because it doesn't contain the element Carbon. This molecule contains Sodium and Chlorine.
Answer:
similarities:
1- both are nucleic acids ( made up of nucleotides )
2- each nucleotide is formed of sugar ring, phosphate group and nitrogenous base.
3- both of them contain the nitrogenous bases adenine, cytosine and guanine.
differences:
1-DNA is longer
2-DNA is the storage form of all genes while RNA has 3 types. messenger RNA which is a message of certain codes, ribosomal RNA which enters in the structure of ribosomes (synthesize proteins) and transfer RNA which carries amino acids and helps in transcription process.
3-DNA contains thymine base while RNA contains uracil
4- DNA is more stable and not easily hydrolyzed.
