The four organelles in eukaryotes are:
- Nucleus: contains the DNA which is synthezised
- Ribosomes:synthesizes the proteins
- Rough endoplasmic reticulum: transports the proteins
- Golgi apparatus/complex/body: where the proteins are chemically modified and then sent out to different parts of the cell.

What organelles do cells need in order for active transport to occur?
Cells need organelles such as ATP-powered pumps, transport proteins, and vesicles for active transport to occur. These organelles help in moving molecules and ions across the cell membrane against their concentration gradient, requiring energy input. Active transport is essential for maintaining proper cellular function and homeostasis.
What are the three main categories of organelles within the cytoplasm?
(1) organelles that produce proteins within the cell; (2) organelles that produce energy in the cell; and (3) specialty organelles. All of these organelles are active within the cytoplasm to help make the cell function correctly.
How do intermediate filaments interact with motor proteins in cellular processes?
Intermediate filaments provide structural support and stability to cells, while motor proteins help transport cellular materials. In cellular processes, motor proteins can interact with intermediate filaments to help move organelles and other components within the cell. This interaction allows for proper organization and functioning of the cell.
Does exocytosis involve the use of proteins?
Yes, exocytosis involves the use of proteins to help transport molecules out of a cell.
What role do peripheral proteins play in the transport of molecules across the cell membrane, particularly in the context of transport proteins?
Peripheral proteins play a crucial role in assisting transport proteins in moving molecules across the cell membrane. They help in the recognition and binding of specific molecules, as well as in the regulation of transport protein activity. This collaboration ensures efficient and selective transport of substances in and out of the cell.

What makes proteins other than ribosomes?
Proteins are made by ribosomes through a process called protein synthesis. However, other cellular organelles, like the endoplasmic reticulum and Golgi apparatus, also play roles in processing and modifying proteins after they are made by ribosomes. These organelles help proteins fold correctly, add necessary modifications, and transport them to their final destinations within the cell.
What suspends the organelles and holds them in place?
The intracellular matrix suspends organelles. Mainly it is the microtubules that originate from the centrosome. They grow out and attach to organelles and help move them outwards and inwards. Like a fishing effect.

Which mmolecules help control movement of substances through cell mmembrans?
Carrier proteins or transport proteins.
What 2 transport processes use carrier proteins?
Two transport processes that use carrier proteins are facilitated diffusion and active transport. In facilitated diffusion, carrier proteins help move molecules across the cell membrane down their concentration gradient, while in active transport, carrier proteins help move molecules against their concentration gradient by using energy.
What are the parts of the membrane help large molecules pass through it?
Globular proteins.
What organelle helps read the code for making proteins?
Ribosomes are the organelles that help read the code for making proteins. They are responsible for translating the mRNA sequence into a specific amino acid sequence, which eventually leads to protein synthesis.
What are three functional proteins?
control the rate of reactions and regulate cell processes. forms bones and muscles. transport substances in/out of cells or to help fight disease.
Does exocytosis involve the use of proteins?
Yes, exocytosis involves the use of proteins to help transport molecules out of a cell.
What requires the use of the energy and the help of transport proteins to move a molecule across a cell membrane?
Active transport
