Kinase enzymes ______

Biology
2 answers:
allsm [11]3 years ago

Answer:

4..add phosphate groups.

Explanation:

Kinases are the enzymes which are responsible for causing phosphorylation of the target molecule by adding a phosphate group on them from ATP/GTP. The phosphorylation of the target molecule may either cause up regulation or down regulation of the target molecule so we can say that kinases play an important role in modulating the activity of physiological processes in our body. Kinases play a very important role in cellular signaling.

For example: The phosphorylation of enzyme known as glycogen synthase by another enzyme known as GSK - 3β leads to it's activation and up regulates glycogen synthesis (Glycogenesis) while phosphorylation of enzyme GSK - 3β by Akt leads to it's inactivation leading to down regulation of glycogen synthesis.

Answer:

Option D (4), add phosphate groups

Explanation:

Kinase enzymes are responsible for cellular activation. Protein kinase causes phosphorylation of specific amino acids by utilizing ATP as source of phosphate.

It adds phosphate groups (PO43−) and induces biological activity of biomolecules (such as proteins, lipids, and nucleic acids) by changing their conformation thereby activating them .

Human genome consists of several hundreds of kinase encoding genes which are involved in multiple phosphorylation reactions with in the cytoplasm of cells.  

Hence, Option D (4) is correct

Air travel is usually the largest component of the carbon footprint of frequent flyers. A single return flight from London to New York – including the complicated effects on the high atmosphere – contributes to almost a quarter of the average person’s annual emissions. The easiest way to make a big difference is to go by train or not take as many flights.


2 The second most important lifestyle change is to eat less meat, with particular emphasis on meals containing beef and lamb. Cows and sheep emit large quantities of methane, a powerful global warming gas. A vegan diet might make as much as a 20% difference to your overall carbon impact but simply cutting out beef will deliver a significant benefit on its own.

What are some direct and indirect substances produced as a result of photosynthesis?
sertanlavr [38]

Answer:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. This chemical energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water – hence the name photosynthesis, "light", and sunthesis, "putting together". In most cases, oxygen is also released as a waste product. Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
