Which of the following statements correctly describes some aspect of protein excretion in prokaryotic cells? a Prokaryotes are u

nlikely to be able to excrete proteins because they lack an endomembrane system. b The mechanism of protein excretion in prokaryotes is probably the same as that in eukaryotes. c Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. d In prokaryotes, the ribosomes that are used for the synthesis of secreted proteins are located outside of the cell. e Prokaryotes contain large pores in their plasma membrane that permit the movement of proteins out of the cell.

The correct answer is option c: "Proteins excreted by prokaryotes are synthesized on ribosomes attached to the cytoplasmic side of the plasma membrane." Many prokaryotes secrete proteins, especially extracellular enzymes used outside cells and toxins not required by the cell. Just like any other protein, those secreted by prokaryotes are created on ribosomes attached to the cytoplasmic side of the plasma membrane. However, secreted proteins are directed to the general secretion (Sec) pathway for tagging and additional processing.

lana [2441]
Work is defined as being completed when an object shifts as a result of an applied force. It is calculated by multiplying the force exerted by the distance moved as a result of that force. It can be represented as: W = Force x distance W = 84 J = F (7.0 m) F = 12 N I hope this provides clarity.

-BARSIC- [2551]

Response:

The accurate responses are A and D

To clarify:

Russell's theory involves the natural gradients of protons, asserting that four billion years ago, alkaline solutions emerged, leading to slightly acidic oceans (with CO2 levels being approximately a thousand times higher, reacting with H2O to form carbonic acid which results in mildly acidic seas). Acidity signifies proton concentration levels, higher in oceans compared to vent fluids. This variation has resulted in a natural proton gradient across the vent membranes that favored an outside positive polarity, which resembles the electrochemical potential in contemporary cells. This potentially explains why the last universal common ancestors across the three biological domains developed proton pumps.

vlada-n [2515]

Answer:

The correct response is to elevate the rate of cellular respiration within mitochondria.

Explanation:

In mammals such as humans, infections can lead to an increase in body temperature by 2 to 3 degrees Celsius. This rise in temperature is the result of thermoregulation tactics controlled by the host’s hypothalamus, which communicates through integrated signals from the immune system and hormones, thereby initiating a rise in metabolic processes due to enhanced cellular respiration in mitochondria, resulting in elevated body temperature. Mitochondria produce energy as ATP, contributing to body temperature as it’s part of an exothermic process.

The correct response is to elevate the rate of cellular respiration within mitochondria.
