Explanation:

Answer:

Hi Motomasa, you are correct that there is a bit of a misrepresentation, or at least a glossing-over, in the standard description of the function of ATP. The "energy-storing" capacity of ATP is NOT in the forming and breaking of the covalent phosphate to phosphate bonds. ATP -> ADP releases energy by two mechanisms. First because the process of hydrolysing the y-phosphate (the terminal phosphate) releases energy. And second because ATP and ADP are maintained out of equilibrium in cells. The action of utilizing an ATP brings the system closer to equilibrium, which releases energy.

There is a required energy input to break the phosphate to phosphate bond. This is the activation energy. However, the energy released upon hydrolysis and moving the system towards equilibrium are of greater magnitude than the activation energy input. I hope this helps!

The Unique feature of Active sites is that active sites are specific to certain substrates (reactants)

Active sites are specific regions of an enzyme where substrate molecules bind in other to bring about a chemical reaction.

The active site is made up of amino acid which forms temporary bonds with the substrate otherwise known as the binding site and the residues which brings about a reaction of that substrate.

Active sites are specific to certain substrates (reactants). Therefore, option (B) is correct.

Active sites are vital to enzymes, proteins that aid biological processes. They have a distinctive form that matches their substrate molecules. This specificity allows only particular substrates to bind to and interact with the active site, catalysing processes. This is called the "lock and key" or "induced fit" model.

Enzymes' catalytic action depends on active sites. A substrate attaches to an enzyme's active site and changes conformation, lowering the reaction's activation energy. This speeds up the reaction. After the reaction, the products are released and the enzyme's active site can bind to another substrate. Therefore, option (B) is correct.

Answer:

Co2 is released from the pyruvate that is formed during glycolysis, and CO2 is also released during the citric acid cycle.

Explanation:

Cellular respiration in mitochondria produces [tex]CO_2[/tex] as a waste product, exhaled during breathing.

Cellular respiration occurs mostly in mitochondria. During cellular respiration, glucose and other nutrients are broken down to make ATP. This procedure produces [tex]CO_2[/tex]. [tex]CO_2[/tex] from mitochondria diffuses into the circulation.

Breathing exchanges [tex]CO_2[/tex] for oxygen in the lungs from the circulation. Your body releases [tex]CO_2[/tex] when you exhale. This important cycle eliminates unwanted [tex]CO_2[/tex] and supplies cells with oxygen for respiration and energy generation.

Iron is a component of hemoglobin, which enables it to absorb oxygen from the air we breathe and transport it throughout the body.

The iron-containing oxygen-transporting metalloprotein known as hemoglobin, often known by the abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.

The normal ranges for haemoglobin are different for males and females, and they also vary depending on the ethnicity of the population. Additionally, age is a factor, particularly for women.

When you have anemia, your body doesn't produce enough healthy red blood cells to supply your tissues with enough oxygen. Anemia, commonly known as low hemoglobin, can make you feel exhausted and frail.

During replication strands of DNA separate from each other when bonds are broken between nitrogen bases. Therefore, option (C) is correct.

The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the most crucial component of biological heredity.

There are two stages to the beginning of the DNA replication process. To begin, a protein known as an initiator unwinds a portion of the DNA double helix along a very short region. After then, a protein that is known as helicase attaches itself to the DNA strands and breaks the hydrogen bonds that are present between the bases. This results in the two strands of DNA being separated.

When two single strands of DNA are cut apart, a 'Y'-shaped structure is produced that is referred to as a replication 'fork.'
