This is a cellular respiration question, related to biology.
Some processes in our bodies require the use oxygen, others do not.
In this case, the conversion of pyruvic acid to acetyl co-enzyme A and the production of water in the electron transport chain do require oxygen.
If oxygen was not present for pyruvate, it would turn into lactic acid via fermentation. Water in the ETC is formed in the process when NADH and FADH2 are converted to molecular oxygen due to the electron transporters. The protons are then pumped and oxygen is reduced to form H2O.
The are formed by cells building carbohydrates polymers, they use energy
to form glycosidic linkages..the bonds between monosaccarides...which
is made by joining two specific monomers, glucose and fructose.
Answer:
The correct answer will be- to synthesise the ATP molecules in respiration process.
Explanation:
The electron transport chain is the last phase of the cellular respiration which helps in the synthesis of a large number of ATP molecules.
The ATP molecules are synthesized when the energy generated by the movement of protons through CF₀ unit takes place.
The movement of electrons in the chain leads to the movement of proton from the mitochondrial matrix to the intermembrane space. This creates the proton gradient across the membrane which to equilibrate the protons move down the concentration gradient through ATP synthase. The energy while this is used to rotate the ATP synthase which coverts the ADP to ATP.
Thus, to synthesise the ATP molecules in the respiration process.
Answer:
A and E are the correct.
Explanation:
Examples of the structures that determine function:
a) <u>Chloroplasts </u>only found in plant cells. They work to fix the CO2 in the presence of <u>light energy</u> (sunlight) and convert the reactants into <u>sugar molecules (carbohydrates</u>) that can be used by cells for metabolic functioning.
e) <u>Sperm</u> is the male reproductive cell. Motile sperm cells have a tail-like structure that typically <u>move via flagella</u> and requires a water medium in order to swim toward the egg <u>for fertilization</u>.
Other options are not correct because <u>they don't explain their function according to their structure</u>.
