Investigators interested in studying the activation of apoptosis inject cytochrome c into the cytosol of two types of mammalian

cells: cells that are normal and cells in which Bak and Bax have been inactivated by mutation.
How would these cells be predicted to respond?

Answer: Both cell types will undergo apoptosis

Explanation:

cytochrome C functions in the mitochondria and plays an important role in the synthesis of Adenosine Triphosphate (ATP). When a cell receives an apoptosis stimulus Cytochrome C is released from the mitochondria into the cystol to activate caspase cascade thereby committing the cell to the death process. Cytochrome C triggers programmed cell death through apoptosis. Cytochrome C release is caused by swelling of the mitochondrial matrix.

The sun is the unlimite sorcuse of engery true or false
vlada-n [284]
<h2>Answer:</h2>

<em>True.</em><em> Yes the sun is the ultimate source of energy.</em>

Explanation:

  • We all living organism needs energy for their survival like for walking, talking and breathing.
  • Energy is required by every cell for their reproduction, growth and maintenance.
  • We all eat food to get that energy. Food is consists of plants and meat of some animal.
  • These some animals also get food from plant.
  • Plants take sun light to make their food/energy.
  • Sun just provide energy in form of food. It dose not get energy from anywhere.
  • Hence we all are ultimately depends on sun.

Which of the following statements correctly describes some aspect of ATP hydrolysis being used to drive the active transport of
saw5 [17]

Answer:

B) This is an example of energy coupling

Explanation:

Energy coupling is a process by which cells carry out thermodynamically unfavorable, endergonic (energy-requiring) reactions to other exergonic (reactions that liberate free energy) reactions.

Reactions which are endergonic do not occur spontaneously as they result in a decrease in entropy and a positive free energy change, ∆G.

Exergonic reactions occur spontaneously as they result in an increase in entropy and have a negative free energy change, ∆G.

For example, the active transport of ions against their concentration gradients in cells is a non-spontaneous endergonic process which is coupled to the hydrolysis of ATP, an exergonic process in other for the reaction to proceed. ATP hydrolysis phosphorylates an amino acid side chain in the transport protein which then drives the forward process of transport of the ion.

Considering the above,

Option A: The hydrolysis of ATP is endergonic, and the active transport is exergonic is false because ATP hydrolysis is exergonic while active transport is endergonic.

Option B: This is an example of energy coupling is true.

Option C: Both ATP hydrolysis and active transport are spontaneous because they result in an increase in entropy of the system is false because only ATP hydrolysis is spontaneous

Option D: Neither ATP hydrolysis nor active transport is spontaneous is false because ATP hydrolysis is spontaneous.

Option E: ATP is acting as a transport protein to facilitate the movement of the ion across the plasma membrane is false because ATP is not a protein, rather it serves to activate the transport protein by phosphorylating it.

Water is essential for life. Its special properties make water the single most important molecule in plant life. Which propertie
Harman [31]

Answer:

Because water exhibits cohesive behavior.

Explanation:

Cohesive behavior can be explained as a behavior where molecules are attracted to each other.

And this means that,  water molecules are attracted to each  other because of their cohesive behavior. This makes them to be  attracted to other substances, such as the walls of the xylem of plants.

In this case, it is believed that the water molecules behave this  way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.
