Where do light dependent reactions take place

Biology
2 answers:
Mekhanik [1.2K]3 years ago
6 0

Answer:

Thylakoid membrane of the chloroplast.

Explanation:

In the process of photosynthesis, light dependent reaction occurs inside the thylakoid membrane known as lumen of the chloroplast. In light dependent reaction, light is captured by thylakoid membrane present on the chloroplast.

Some integral membrane protein complexes are present in the thylakoid membrane that helping in catalyzes the light reaction. There are 4 major complexes are present in the thylakoid membrane:

1) Photosystem I.

2) Photosystem II.

3) Cytochrome b6f complex.

4) ATP synthase.

These four types of protein complexes are working together to form the products ATP and NADPH.

In this process mainly light absorption, oxygen release, dividing of molecules and formation of high energy molecules such as ATP ad NADPH occurs.

Assume that the mother's genotype is AZ/az, and the father's genotype is Az/aZ, and the recombination rate is 10%. What are the
attashe74 [19]

Answer:

0.45 from mom and 0.05 from dad.

Explanation:

The recombinant progeny might occur due to the crossing over at the time of meiosis in which the exchange of chromosomes occur in the homologous chromosomes of non sister chromatids.

The progeny receives half of their chromosome from the mother and half from the father. The mother 50% AZ and 50% az chromosomes respectively. The 10% recombination has occured due to which the mother chromosomes is reduce upto 45%. The recombinant  10% will be aZ and Az and has 5% frequency. Mom has the ability of az chromosomes is 0.45 %. The father has the genotype 50% Az and 50% aZ. The 10% recombination has occured due to which the father chromosomes is reduce upto 45%. The recombinant will be az and AZ with 5% frequency. So, father has az with 0.05 % probability.

Thus, the answer is 0.45 from mom and 0.05 from dad.

Anna007 [38]

A baker has created a new strain of yeast which contains no cytochrome c gene and no cytochrome c protein. this will affect what the yeast strain can do to obtain energy. what will this yeast strain do more of compared to a normal strain

Will this new strain of yeast obtain more or less free energy from glucose in its growing medium?

Answer: Less because cytochrome c is key to the electron transport chain.

Explanation:

The Cytochrome c is an essential component of the electron transport chain. Without this there will be no oxidation and reduction of iron atom will take place which could convert the ferrous ions to ferric ions. Thus the entire process of electron transport chain and energy production in the form of ATP will be compromised. So, there will be no production of energy in the anaerobic fermentation by yeast.

Slate is a fairly common rock that can be used for roofing shingles. what property makes it most suitable for this use?
Lemur [1.5K]
The property that makes slate most suitable for roofing shingles is that it can be split into thin, flat layers.
This means that the roofs of houses and other buildings can be created from slate in order to cover the tops in the best way possible. Other materials are also often used for this purpose, but slate is one of the most popular ones nowadays because of that property it has.

If the producers in a food web were removed, which of the following changes would most likely occur?
SpyIntel [72]

Answer:

If the producers would be removed in the food web, then the whole ecosystem would fall down and die.

Explanation:

The reason why producers are important in a food chain is because they provide food for the herbivore animals, and then, the carnivore animals kill and eat the herbivore ones, and whatever is left, is eaten by the decomposers. So, if we remove the root of the tree (producers), then can the tree(rest of food web) survive? The simple answer is NO.

So, Hence, the ecosystem won't be able to last long, all animals will die.
