A cell can only grow so large in size, because
sweet-ann [11.9K]
<span>A cell can only grow so large in size because its ability to exchange materials is affected by a growing surface-to-volume ratio. Nature designed cells to be small in size because of the network of membranes passing through it. If cells grow any bigger, membranes in it will not be able to pass through its different parts and perform their purpose.


A cell is a network composed of many organelles (e.g. mitochondria, nucleus), that communicate and work together to provide bodily functions. The cell is small so that communication between organelles will be faster and much easier. When cells are small they can be easily repaired when damaged and replicated when needed.</span>

Place the following steps of endomembrane system function in the correct order.
maks197457 [2]

Answer:

D

Explanation:

<em>The correct option here would be</em><em> D</em><em>.</em>

The endomembrane system refers to a group of membrane-based organelles whose primary function is to synergistically work together to modify, package, and transport lipids and proteins. The system includes organelles such as the lysosome, the nuclear envelope, the endoplasmic reticulum, and the Golgi apparatus.

For an endomembrane system function involving a protein, the protein would first of all need to be synthesized by the ribosome - the free ones or the ones attached to the rough endoplasmic reticulum. Thereafter, the synthesized protein would then be folded or packaged into transportable vesicles. The vesicles are then received by the Golgi apparatus which further modifies the proteins before transporting them accordingly.

Hence, the correct order of a typical endomembrane system function would be:

  1. <em>Ribosomes on the RER synthesize proteins.</em>
  2. <em>Proteins are packaged into transport vesicles.</em>
  3. <em>Golgi apparatus receives transport vesicles from the RER.</em>
  4. <em>Proteins are modified by the Golgi apparatus.</em>
  5. <em>Modified proteins may be secreted from the cell by exocytosis.</em>

What is the essence of the catalase test?
garik1379 [7]

Explanation:

Catalase test demonstrate the presence of an enzyme called catalase, that catalyses the release of oxygen from hydrogen peroxide. It is used to tell the difference between the non-catalase producing bacteria from those bacteria that produces an enzyme catalase. Catalase is produced by the bacteria that respire using oxygen. If an organism produces catalase, bubbles of oxygen are produced when hydrogen peroxide is added to it.
