Explanation:
Photosynthesis is a process taking place in the green plants which are involved in the formation of the glucose molecule using Carbon dioxide and water in the presence of sunlight.
The process of photosynthesis takes place in two phases:
1. Light-dependent phase
2. Light independent phase
<u>Light-dependent phase
</u>
Light-dependent phase takes place in the thylakoid membrane where the Photosystem I and II are present.
The photosystem II absorbs the sunlight of 680 nm wavelength which excites the electron of the chlorophyll. The electron moves in the photosystem and through the reaction center-exit the photosystem and enters the electron transport chain.
The electron is then transferred via the electron carriers like plastoquinone, cytochrome, and plastocyanin and is transferred to photosystem I which absorbs the light at 700 nm. From here the electron is taken by ferrodoxin and form NADH.
The electron then reaches the ATP synthase and forms the ATP molecules thus ATP and NADPH are formed in the reaction but the loss of electron in chlorophyll is fulfilled by the water molecule which on hydrolysis provides the electrons and stabilize the structure.
<u> Light independent phase
</u>
The phase during which the Rubisco enzyme binds with the carbon dioxide and forms 3-PGA. This 3 PGA is then reduced to G3P which requires the 6 ATP molecules. The G3P molecule then forms 1 molecule of glucose and the Rubp is again regenerated.
The general trend for hormones after ovulation as an individual when it approaches menstruation is that hormone levels generally rise. This increase levels of estrogen and progesterone would cause a negative feedback to the hypothalamus and the pituitary, which would result in the decline of the FSH and LH. BTW: Not to be TMI but i started mine and there is nothing to be scared of.
plastic items take up to 1000 years to decompose in landfills. But plastic bags we use in our everyday life take 10-20 years to decompose, while plastic bottles take 450 years.
I hope this helps
Answer:
There is 46 pairs of chromosomes.
mRNA
Messenger RNA is used to copy and encode genetic information from DNA base pairs by forming complementary strand of RNA molecule from the nucleus of the cell to the cytoplasm.
tRNA
Transfer RNA reads sequence of nucleotide from messenger RNA and translate them into proteins or amino acids during proten synthesis.
Transcription
This is the first step in gene expression where information from DNA is copied into a complementary strand of RNA molecule using RNA polymerase enzyme.
Translation
Messenger RNA made from the process of transcription travels to the ribosomes in the cytoplasm where proteins are produced using transfer RNA to copy the information.
The use of DNA to make proteins.
Through gene expression (central dogma of biology), the DNA molecule carries information, a gene code, in form of base pairing sequences that are transcribed to RNA and further translated to functional proteins or amino acids.
