The energy from glucose is used by the ETC to mediate the transfer of electrons and also the proton transfer across the membrane so that ATP can be generated to be used in various life processes.

ETC is the Electron Transport Chain. It occurs in the inner mitochondrial membrane. The purpose of ETC is to generate more and more ATP. This occurs by the transfer of electrons through a series of transporters which also mediates the proton transfer across the membrane. This generates a gradient and when energy is released from that gradient it is used in the generation of ATP.

ATP is Adenosine Triphosphate. It is the energy form prevalent in most of the living organisms. The hydrolysis of ATP releases energy which is used by an organism.

A person who contains one copy of a genetic trait's recessive allele but does not express the trait is said to be a carrier.

As a result of having a dominant allele that controls how the trait manifests, carriers do not manifest the recessive trait.

A person needs two copies of the recessive gene, one from each parent, in order to manifest a recessive characteristic. Hence, individuals that carry a recessive allele can pass it on to their progeny without displaying the trait.

Yet, there is a 25% possibility that if both parents carry the same recessive gene, their kid will inherit two copies of the allele and manifest the recessive characteristic.

This pedigree is consistent with autosomal dominant inheritance.

The reason is that affected individuals marrying unaffected individuals have affected children, so the trait is dominant. Males do not pass the trait to all their daughters, so it cannot be X-linked dominant.

Autosomal dominant inheritance is a pattern of inheritance in which a single copy of an abnormal gene (located on one of the autosomes, which are the non-sex chromosomes) from one parent is enough to cause a genetic disorder or disease.

In this inheritance pattern, the gene responsible for the disorder is dominant, meaning that a person who inherits one copy of the abnormal gene will develop the disorder. Autosomal dominant disorders often appear in every generation of an affected family and can affect both males and females equally.

Explanation:

Acids prevent browning because they react with the oxygen that comes into contact with the surface of the sample. Once all the acid (or whatever else is covering the surface) has reacted with the oxygen or the acid has degraded or washed off, then the sample will start to brown again. Stronger acids, like lemon juice, can even denature the enzyme. This means that the enzyme can no longer perform its original function because of its environment.

Answer:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lack soil.

Secondary succession is one of the two types of ecological succession of a plant's life. It is the process started by an event (e.g. forest fire, harvesting, hurricane, etc.) that reduces an already established ecosystem (e.g. a forest or a wheat field) to a smaller population of species, and as such secondary succession occurs on preexisting soil whereas primary succession usually occurs in a place lacking soil.

Explanation:

Primary succession takes time for completion around 1000 years, whereas secondary succession area takes 200 years for completion. In primary succession, there is a lack of soil and humus for the sustaining of life whereas, in secondary succession, soil and humus are present with some organisms.

A Secondary succession can take a few hundred years.

Both RTK (Receptor Tyrosine Kinase) activation and GPCR (G-protein coupled receptor) activation can lead to downstream activation of GBPs, kinases, and transcription factors.

RTK activation and GPCR activation are two distinct signalling pathways involved in cellular communication. They can converge on common downstream signalling molecules. One such molecule is GBPs (GTP-binding proteins) which can be activated by both RTK and GPCR signaling. GBPs play a crucial role in transmitting signals and regulating various cellular processes.

Additionally, both RTK and GPCR activation can result in the activation of kinases. Kinases are enzymes that catalyze the transfer of phosphate groups to other proteins, thereby regulating their activity. The activation of kinases can trigger a cascade of signalling events leading to diverse cellular responses.

Moreover, both RTK and GPCR activation can ultimately lead to the activation of transcription factors. Transcription factors are proteins that bind to specific DNA sequences and regulate gene expression. They play a vital role in controlling the synthesis of proteins and influencing cellular functions.

On the other hand, Notch activation and Wnt activation are independent signalling pathways that are not directly associated with either RTK or GPCR signalling. Notch signalling is a highly conserved pathway involved in cell fate determination and development, while Wnt signalling regulates various processes during embryonic development and adult tissue homeostasis. Although they have critical roles in cellular signalling, they do not lie downstream of RTK or GPCR activation.
