What is the importance of enzymes?

User Avatar

Asked by Wiki User

Enzymes break down proteins for use in the body, and they're to speed up the reaction of the product.

eg - photosynthesis enzymes are used to speed up the reaction to make it into glucose and oxygen.

Enzymes (pronounced /ˈɛnzaɪmz/) are proteins that catalyze (i.e., increase the ratesof) chemical reactions.[1][2] In enzymatic reactions, the molecules at the beginning of the process are called substrates, and they are converted into different molecules, called the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.

Which science is the most complex chemistry or biology or physics?

User Avatar

Asked by Wiki User

The most complex science between the 3 is biology followed by chemistry and next is physics.

This is because Biology as a science encompasses the nature and laws of life (scientifically), which means that as a science that studies life it ranges from the microscopic to macroscopic level of understand and acquiring knowledge about life. Biology in microscopic level includes the study of the cells, its components and the macromolecules that makes up for each components , how they work and what makes an organism alive up to the macroscopic level that includes the ecology understanding how organism interact with each other and with their environment, how environmental changes drives evolution and how evolution changes the way life goes with the living organisms. Hence, biology includes both understanding the science of chemistry and physics.

Do cancer cells divide?

User Avatar

Asked by Wiki User

Yes, cancer cells divide. Uncontrolled cell division is one of the hallmarks of cancer. Normally, cell division is tightly regulated by the cell cycle, a series of steps that ensure cells divide in an orderly manner to replace old or damaged cells and to support growth and development. However, cancer cells lose this regulation and can divide uncontrollably, leading to the formation of tumors.

The uncontrolled division of cancer cells can result from various genetic mutations and abnormalities that disrupt the normal regulatory mechanisms of the cell cycle. These mutations can affect genes that control cell growth, cell division, DNA repair, and cell death (apoptosis).

Cancer cells may also have the ability to evade signals that normally inhibit cell division, allowing them to continue dividing even when external signals would normally prompt them to stop.

Moreover, cancer cells often have the ability to bypass the normal mechanisms that limit the number of times a cell can divide (known as replicative senescence), allowing them to continue dividing indefinitely.

The uncontrolled division of cancer cells can lead to the formation of tumors, which can grow and invade surrounding tissues. This unregulated growth and invasion can lead to the spread of cancer to other parts of the body, a process known as metastasis.

Understanding the mechanisms of cell division in cancer cells is crucial for developing effective treatments that target the specific vulnerabilities of cancer cells while minimizing harm to normal cells. Many cancer treatments, such as chemotherapy, radiation therapy, and targeted therapy, work by interfering with various aspects of cell division and growth in cancer cells.

Which family of elements are called basis of life?

User Avatar

Asked by Wiki User

Carbon, Hydrogen, Oxygen, Nitrogen.

They can form the four moleccules Carbon dioxide(CO2), Water(H2O), Methane(CH4) and Ammonia(NH3). These four molecules are the 'brick' that build to make life.

What is the purpose of a bodysuit?

User Avatar

How does a nitrogenous base pair with DNA?

User Avatar

Asked by Wiki User

In DNA, nitrogenous bases pair according to specific rules known as complementary base pairing. adenine(A) pairs with Thymine (T) and Cytosine(C) pairs with Guanine (G). This is due to the hydrogen bonds between these bases: two between A and T, and three between C and G. These pairings allow the double helix structure of DNA and enable the accurate replication of DNA during cell division.

Is a spider and web a living or nonliving thing?

User Avatar

Asked by Wiki User

A spider is a living thing because it has vital functions (Nutrition, Respiration, Movement, Growth, Sensitivity, Excretion and Reproduction). However a spiderweb/cobweb is a non-living thing because it does not have any vital functions from the above.

What are two kinds of RNA and their jobs?

User Avatar

Asked by Wiki User

the two types of RNA is Messenger RNA and transfer RNA. Messenger RNA copies the coded message from the DNA in the nucleus, and carries the message to the ribosome in the cytoplasm. transfer RNA carries amino acids to the ribosome and adds them to the growing protein.

Explain why a virus might exist for years and only become active once it comes into contact with a living cell?

User Avatar

Asked by Wiki User

A virus is debatably not a living thing, it stores no energy and "tricks" the cell into expending its own energy which the virus then uses for its "evil deeds"
