24. Carbohydrates, lipids, proteins and nucleus acids.

25. The element we can find in proteins but not in carbohydrates is nitrogen.

26. Carbon atoms are the backbone of all organic material or compound.

27. I would say the saturated fats contain at least only single bonds in the carbon chain.

28. The monomers that make up proteins is called amino acids.

29. Enzymes basically create a chemical reactions in the body. Enzymes speed up the rate of a chemical reaction to help support life. Enzymes that are found in your body help to perform very important task including building muscle, destroying toxins and breaking down particles of food during digestion.

Marysya12 [62]

Answer:

D. 4E-BP1 binding to elF4E prevents loading of the mRNA onto the ribosome.

Explanation

In eukaryotic organisms, the eIF4E translation initiation factor functions by directing the ribosomes to the 5'-terminal cap structure of the messenger RNA (mRNA) in order to start the translation. Moreover, phosphorylation is a posttranslational modification of specific amino acids on proteins that play diverse cellular functions by altering protein stability, location, and/or enzymatic activity. It has been shown that elF4E phosphorylation is increased in response to cellular stimuli that induce translation in the ribosomes (e.g., growth factors, hormones, etc). The eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1) is a repressor of mRNA translation which is phosphorylated and inactivated by growth factors and hormones, thereby inhibiting 4E-BP1 binding to elF4E and consequently activating translation.

Which of the following represents an important outcome of looping?

frutty [35]

Answer:

a. establishment of left-right asymmetry

Explanation:

Cardiac looping is the process in which the heart transforms itself from a straight embryonic heart into a loop that is wounded helically.
The looping of the heart takes place on the 23rd day of development.
As a result of this looping, there is bending of the cranial portion of the heart to the towards the right end and the caudal portion of the heart towards the left end.
At the end of this looping the atrium takes up a dorsal and cranial position and the ventricle is displaced towards left.
Thus, the outcome of looping is the establishment of left-right asymmetry.

What are some basic steps to saving tropical rainforests?

sp2606 [1]

Teach others about the importance of the environment and how they can help save rainforests. Restore damaged ecosystems by planting trees on land where forests have been cut down. Encourage people to live in a way that doesn't hurt the environment. Establish parks to protect rainforests and wildlife.

Hope this helps

In what organelle do the kreb’s cycle and the electron transport chain take place?.

gtnhenbr [62]

Answer:

This would be the MITOCHONDRIA!

Concept(s):

Mitochondria

- An organelle in the cytoplasm of cells that functions in energy production.

Organelle

- A specialized [art pf a cell having some specific function; a cell organ.

Krebs's cycle

- A cycle of enzyme-catalyzed reactions in living cells that is the final series of reactions of aerobic metabolism of carbohydrates, proteins, and fatty acids, and by which carbon dioxide is produced, oxygen is reduced, and ATP is formed.

Electron

- An elementary particle that is a fundamental constituent of matter, having a negative charge of 1.602 × 10-19 coulombs, a mass of 9.108 × 10-31 kilograms, and spin of 1/2. and existing independently or as the component outside the nucleus of an atom.

Explanation:

In what organelle do both the Krebs cycle and the electron transport system occur?

Mitochondrion

The mitochondria's sole function is to provide the cell with energy, and the only way it can do this is by drawing its power from the ATP molecules created by the Krebs cycle and the electron transport system.

What is the significance of an electron transport chain? Like the energy is already produced in Krebs cycle, so why does the Electron transport chain run?

The chemical processes fueled by enzymes are known as the Kreb's cycle. Since these processes need certain enzymes, they happen inside the mitochondria. 32 molecules of ATP are produced by the Kreb's cycle for every molecule of glucose, Carbon IV oxide, and hydrogen ions.

In the hydrogen ion transport chain, hydrogen ions can enter through a variety of acceptor molecules, such as NAD (nicotinamide adenine), which produces NADH2. Their hydrogen is taken up by oxygen to create water, which releases energy. ADP uses this energy to create ATP.

How does the Krebs cycle and electron transport chain work?

A closed loop is the Krebs or citric acid cycle. The substance utilized in the first step is renewed in the pathway's final stage. In each of the cycle's eight phases, redox, dehydration, hydration, and decarboxylation processes result in the production of two carbon dioxide molecules, one GTP/ATP molecule, and reduced forms of NADH and FADH.

Electron transport is a sequence of redox events where electrons are quickly transferred from one component to the next until they reach the end of the chain where they reduce molecule oxygen to produce water. These redox reactions resemble a relay race or bucket brigade.

The electron transport chain, a sequence of electron transporters that are involved in redox processes, is the source of the majority of the ATP produced during the aerobic catabolism of glucose. As a result, hydrogen ions start to build up in the matrix space. As a result, a concentration gradient develops, allowing hydrogen ions to migrate through ATP synthase and out of the matrix region. The catalytic activity of ATP synthase, which phosphorylates ADP to produce ATP, is driven by the current of hydrogen ions.
