Which product is the result of light reactants in photosythesis

1 answer:

8 0

The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.

<u>What is the end product of light reaction in photosynthesis?</u>

The energy from sunlight is converted into a small amount of ATP and an energy carrier called NADPH. Together with carbon dioxide, these are used to make glucose (sugar) through a process called the Calvin Cycle. This is the things happening during light reaction of photosynthesis .

Hope this helps:)

The lac operon in E.coli regulates genes that code for enzymes required for breakdown of lactose. The lac operon is____ operon t

user100 [1]

Ans.

Lac (lactose) operon in a type of bacterial operon, which shows a cluster of genes that are regulated by a single promoter. It is composed of an operator, promoter, a terminator, and three structural genes (lacA, lacY, and lacZ), which are responsible for the transport and breakdown of lactose.

The lac operon is an inducible operon as it gets activated in the presence of lactose and expressed its functional genes in the form of proteins (or enzymes) for lactose metabolism.

Thus, the correct answer to be fill in first blank is 'inducible' and in second blank is 'lactose.'

What are the disadvantages of transmission electron microscope?

Arada [10]

A Transmission Electron Microscope is an impressive instrument with a number of advantages such as:

TEMs offer the most powerful magnification, potentially over one million times or more

TEMs have a wide-range of applications and can be utilized in a variety of different scientific, educational and industrial fields

TEMs provide information on element and compound structure

Images are high-quality and detailed

TEMs are able to yield information of surface features, shape, size and structure

They are easy to operate with proper training

Disafvantages:

Some cons of electron microscopes include:

TEMs are large and very expensive

Laborious sample preparation

Potential artifacts from sample preparation

Operation and analysis requires special training

Samples are limited to those that are electron transparent, able to tolerate the vacuum chamber and small enough to fit in the chamber

TEMs require special housing and maintenance

Images are black and white

A. The city receives direct sunlight all over the year since it is in tropical zone (less than 30 degrees in latitude). The solar intensity will not cause a significant difference in temperature since the solar intensity itself does not vary significantly.
<span>d. The decrease in ozone will increase solar intensity and the amount of ultra-violet rays. It may lead to a higher chance of sunburn. People may also have skin cancer because of ultra-violet.
I dont really know b and c neither.</span>
