Answer:

Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.

Cells have an organelle known as 'mitochondria' which has ATP molecules in it. These ATP molecules generates energy for the cell to function properly.

Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy.

This process is called 'cellular respiration'.

The process is happens in all the cells in our body.

Oxygen is used to oxidize food, main oxidized food is sugar(glucose).

Paul [167]

Answer:

Both the PKA and IP3 levels increases. Hence, the correct answer is a and b.

Explanation:

Forskolin refers to a drug that increases the levels of cAMP or cyclic AMP by stimulating the enzyme adenylyl cyclase. The cAMP is an essential secondary messenger that ensures proper biological response of cells to hormones and other signals and also takes part in communication between the cells.

When Forskolin increases the levels of cAMP, it will stimulate the enzyme PKA or protein kinase A and at the same time also enhances the intracellular concentration of Ca2+ and IP3 (inositol 1,2,5 triphosphate).

Setler [38]

The digeorge syndrome is a genetic disorder, which caused by the deletion in the chromosome number 22. This disease is characterized by the congenital heart disease, immunodeficiency, and hypocalcemia.

In this case, the most frequent clinical manifestation is hypocalcemia. Hypocalcemia is the condition, in which the blood calcium level would be declined to a significant level.

How many generations does it take for a single bacterial cell to become 256 bacterial cells? (hint, don't forget to count the fi

Tpy6a [65]

Bacteria is a unicellular organism which can multiply very fast by binary cell division.
To get a number of divisions required for cell division: you can use the formula: 2 $x^{number of generations}$ = number of bacteria
To get 256 bacteria:
2 $x^{n}$ = 256 (you can solve this equation by a calculator)
so: n = 8 generations

With this formula the first bacteria is taken into consideration since 1 bacteria gives two, then the two give four, then eight, 16...

azamat

Answer:

1) abiotic synthesis of small organic molecules (monomers)

2) joining of monomers into polymers

3) packaging of these molecules into protobionts, droplets with membranes that maintained a distinct internal chemistry

4) origin of self-replicating molecules that eventually made inheritance possible
