Answer:

Control: sat in silence

Experiment: with music

Independent: The music or no music

Dependant: Their heart rate and pulse

Explanation: Control group: is the one that sat in silence

The one that listened to music is the Experimental Group

The independent variable is the thing that they change, the music

And the dependant variable is what is being measured, their pulse and heart rate

Adenosine triphosphate (ATP) is the energy currency of a cell. All of the following statements regarding ATP are true expect one
creativ13 [48]

Adenosine triphosphate (ATP) is a cell's energy currency. All of the following statements about ATP are true, except ATP is used to lower activation energy in enzymatic reactions.

  • A) ATP is used to lower the activation energy in enzymatic reactions.

<h3>How does ATP affect enzyme activity?</h3>

Enzymes allow chemical reactions to proceed with activation energy provided by the catabolism of ATP. When cells convert glucose and oxygen into carbon dioxide and water, they use 2 molecules of ATP as activation energy and gain 36 to 38 molecules of ATP in return. Without enzymes, this would not be possible.

For both actin and microtubule polymerization, nucleotide hydrolysis is important for ______. Group of answer choices promoting
jarptica [38.1K]

Answer:

For both actin and microtubule polymerization, nucleotide hydrolysis is important for decreasing the binding strength between subunits on filaments.

Explanation:

Cytoskeletal filaments are common to eucaryotic cells and are impotartant to the spatial organization of cells. Intermediate filaments provide mechanical strength and resistance to shear stress. Microtubules determine the positions of membrane-enclosed organelles and direct intracellular transport. Actin filaments determine the shape of the cell's surface and are necessary for whole-cell locomotion. A large number of accessory proteins are present that link the filaments to other cell components, as well as to each other. Accessory proteins are essential for the assembly of the cytoskeletal filaments in particular locations, and it includes the motor proteins that either move organelles along the filaments or move the filaments themselves.

Actin filaments and microtubules are assembled with expenditure of energy i.e the ATP/GTP tightly bound to actin/tubulin is irreversibly hydrolyzed to ADP/GTP during the assembly process, and liberation of Pi in the medium occurs subsequent to the incorporation of subunits in the polymer. Pi release acts as a switch, causing the destabilization of protein-protein interactions in the polymer, therefore regulating the dynamics of these fibres. The progress is made in four areas: the chemistry of the NTPase reaction; the structure of the intermediates in nucleotide hydrolysis and the nature of the conformational switch; the regulation of parameters involved in dynamic instability of microtubules; and the possible involvement of nucleotide hydrolysis in the macroscopic organization of these polymers in highly concentrated solutions, compared with the simple case of a equilibrium polymers.

30. One cause of muscle soreness is
xenn [34]

Answer:

c. lactic acid fermentation

Explanation:

If we did alcoholic fermentation, working out would make us feel drunk, not sore. This is only done by yeasts (a type of fungus) and bacteria. Glycolysis is simply an anaerobic process that occurs with fermentation and also regular aerobic respiration. It doesn't cause any soreness on its own. The Krebs cycle is the second major part to cellular respiration; it produces 6 NADH's, 2 FADH2's, 4 CO2's and 2 ATP; it's not involved in creating any soreness, as cell respiration does not create soreness. That leaves lactic acid fermentation, which we, bacteria, yeasts, and other organisms do. This is what we do when we run out of ample oxygen while doing some strenuous activity. Glycolysis is done with it. Glycolysis, however, relies on NAD+ to create ATP we need to maintain the same level of activity, lactic acid is produced as it accepts the 2 electrons and [H+] NAD+  should accept.
