Hydrogen peroxide is a natural byproduct of cellular metabolism in the human body. This product can be considered a free radical.
<h3>What is free radical?</h3>
A free radical may be described as any molecular species able to impartial life that consists of an unpaired electron in an atomic orbital. The presence of unpaired electron effects in sure not unusualplace homes which can be shared via way of means of maximum radicals. Many radicals are volatile and especially reactive.
These free radicals were recommended to be chargeable for reperfusion-triggered cardiac lovely and reperfusion-triggered arrhythmia. Hydrogen peroxide (H2O2) is frequently used as an experimental supply of oxygen-derived unfastened radicals.

4. No infinitives are used. Sentence 4 contains a gerund.
5. includes Steve writing about himself in the first person.
That what i got and if any incorrect then sorry I try my best.
Answer:
B) cAMP
Explanation:
Phosphodiesterase is an enzyme that breaks a phosphodiester bond, for example in molecules such as cAMP and cGMP. So, phosphodiestarases are are regulators of signal transduction: regulate the duration of signaling pathway.
Caffeine is central-nervous-system stimulant and the mechanisms of its action usually are: mobilization of intracellular calcium or inhibition of specific phosphodiesterases.
Explanation:
- Light energy is absorbed and transferred to the reaction center.
- A water molecule is split.
- Electrons are transferred from photosystem II to photosystem I.
- ATP is synthesized from ADP and inorganic phosphate.
Further Explanation:
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
The chloroplast is a membrane bound organelle found in plants. It contains several invaginations of a plasma membrane called the thylakoid membrane. This contains chlorophyll pigments, in stacks called granum, while the internal spaces of the organelle are called the lumen. Liquid surrounds the granum, forming the stroma.
During the light reaction:
- Light is absorbed by pigments in phosystem II (PSII). This energy is transferred among pigments til it gets to the reaction center, and is transferred to P680; this promotes an electron to a higher energy level where it then goes to an acceptor molecule.
- Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent.
- the electron moves down an electron transport chain (ti PS I)where it experiences continuous energy loss. This energy fuels the pumping of H+ from the stroma to thykaloid, leading to the formation of a gradient. The H+ move along their gradient and cross through ATP synthase, into the the stroma.
- ATP synthase converts ADP and Pi to the energy storage molecule ATP.
- The electron gets to photosystem I where it goes to pigments at P700. It absorbs light energy, the electron is promoted to a higher energy level, and passed to an electron acceptor. This leaves a space for another electron which is then replaced by one from photosystem II.
- in the ETC, the molecule NADP is reduced to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.

Answer:
8 different combinations of gametes can be produced by this mosquito, assuming no homologous recombination between chromosomes
Explanation:
The mosquito has 6 chromosomes. This means that means it has 3 pairs of homologous chromosomes. Basically, we can assume the number of different gametes by 2 to the power of 3 as their are 3 homologous pairs. This means 2×2×2 which will be equal to the amount of eight. Hence, eight different combination of gametes will be produced.
