Answer:
The correct answer will be option- ATP concentrations in a cell are usually much higher than the equilibrium concentration for ATP hydrolysis
Explanation:
Adenosine Triphosphate or ATP is known as the energy currency of the cell as it provides energy during the metabolic reactions.
The study on the structure of ATP revealed that it contains ribose sugar attached with three phosphates group bonded to each other via two phosphoanhydride bonds.
The metabolic reaction usually uses Magnesium bonded ATP as Magnesium covers the negative charge of the triphosphate which allows the ATP to bind hydrophobic clefts of the active site.
The ATP also transfers the adenyl group to the nucleophile which helps generate the pyrophosphate.
Answer:
The most correct statement is d. Ganglia associated with afferent nerve fibers contain cell bodies of sensory neurons.
Explanation:
Ganglia are considered a group of nerve cell bodies and are responsible for carrying nerve impulses. The sensory nerve ganglion collects and modulates the sensory information, and constitutes the deposits of the neuronal somas of the primary afferent fibers of the sensory system. This consists of afferent nerve cell bodies, efferent nerve cell bodies, and neuronal axons. It acts by receiving signals from the periphery and sending them to the brain, that is, it has an afferent function. Afferent fibers transmit sensory stimuli from the skin, mucous membranes and deep structures, for this, ganglia are constituted by abundant distinctive neuronal connections, which are responsible for receiving these signals and fulfilling their afferent function.
Photosynthesis takes in sunlight and carbon dioxide, along with water and nutrients, so the plant can make energy. That energy is used for cell growth and repair, producing seeds, etc. The plant will exhale oxygen as a byproduct of photosynthesis.
Similarly, cellular respiration is also used to create energy for the host organism. However, the cells take in oxygen along with something like complex sugars (ie the stuff you eat) and use those components to form energy for the cell. The energy for human cells is useful for cell growth and repair, nerve impulses, muscle contractions, etc. Basically anything you can think of that the human body needs to do on a regular basis, it requires energy to do so. A byproduct of cellular respiration is carbon dioxide, which is exhaled out to the environment. The plant will then absorb the CO2 to keep the cycle going.
In short, both processes are used to make energy for the cell. The differences is what the inputs for each process require. Photosynthesis takes in sunlight, water, and carbon dioxide (and other plant nutrients), and exhales oxygen. Cellular respiration takes in oxygen and complex sugars (from plant material or other animals) and exhales carbon dioxide.
That <u>all cells contain nuclei </u>is NOT a component of the cell theory
Explanation:
Not all cells contain a nuclei. Cells are even categorized based on this attribute. Eukaryotic cells have a nucleus while prokaryotic cells do not. This property, therefore, cannot be used to categorize all cells. Prokaryotic cells have a nucleoid, which is not a true nucleus, but only a region in the cell where the genetic material of the cell can be found.
The other 3 choices are the universally-accepted tenets of the cell theory;
-cells are the basic unit of organization in organisms
-all living things are made of cells
-all cells come from pre-existing cells

Answer:
D. Lipids
Explanation:
Lipids include any of a class of organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.
