Explain the impact of the increased carbon dioxide emissions on the environment

Climate change
Greenhouse effect

Some heat energy from the Earth’s surface escapes into space. If too much heat energy escaped, the planet would be very cold. However some gases in the atmosphere can trap escaping heat energy, causing some of it to pass back to the surface.

These are called greenhouse gases, and they keep our planet warm, which is a good thing. Carbon dioxide is an important greenhouse gas.

Increasing carbon dioxide levels

Humans burn fossil fuels such as oil, coal and natural gas. The energy released is used to power cars and other machines, to generate electricity, and to keep buildings warm. The burning fuel releases waste gases, including carbon dioxide. As the human population increases, more fuel is used, and more carbon dioxide is released.

Global warming

The extra carbon dioxide increases the greenhouse effect. More heat is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. The increase in global temperature this causes is called global warming.

What are characteristics of allosteric enzymes? A. They tend to have a hyperbolic curve of vs. [S]. B. They may have binding sit
nika2105 [10]

Answer:

Option (B), (D) and (E).

Explanation:

Allosteric enzymes may be defined as the enzymes that an change their  conformation ensemble after binding to an effector molecule. They play important role in cell signalling and metabolic pathways.

Allosteric enzymes do not obey Michaelis- Menten kinetics. They have two binding sites regulatory site and active site. They contain multiple subunit and exist in more active and less active form depending on the type of substrate and regulatory molecule.

Thus, the correct answer is option (B), (D) and (E).
