00:01 Okay, i want to answer this question.

00:01 Let's talk about macromolecules.

00:03 Question number one says this type of macromolecule functions as functions as enzymes in chemical reactions.

00:08 And, well, the answer for this question is going to be proteins.

00:11 Okay, we don't even need to discuss this because practically the enzymes are proteins and they have the property to catalyze reaction, chemical reactions.

00:20 Okay.

00:22 Option or question number two says, which is the following correctly matches the organelle and its function? okay, so let's answer this question.

00:29 Option a says lysosome make carbohydrates and this is false because the function of lightosome is cell digestion okay to break down some molecules option b says cytoskeleton and cell digestion and this is false because cell digestion is the function for lysosome.

00:45 Then we have options here that says goff endoplasmic reticulum make proteins and this is true and this is the answer for this question because the govendoplasmic reticulum is a membrane bound organelle that has viobosomes attached to its membrane.

00:58 It has ribosomes attached to its membrane and gybosomes or the function of gyrvibosomes is to produce proteins then the function of gauphin of lepidiculum is going to be produced proteins okay to produce proteins option this is mitochondria photosynthesis and this is false okay because the function of mitochondria is to produce atp while for synthesis is a function that occurs in your classes the next question says cells have a golica paradox in order and let's look at the options.

01:28 Option aces process, process molecules to deliver them to the location in the cell.

01:33 And this is true and this is the answer for this question, because, for example, in the secretary pathway, where you produce your mrna in the nucleus and then this mra is going to be translated and produce a protein in the agrounding of the metacetulum.

01:46 This protein is going to be secreted in vesicles to this golgi apparatus.

01:51 And once in this work apparatus, this protein is going to develop some modifications after it is going to be released again in vesicles to the target destination.

02:04 Okay, for example, to the cell membrane or outside of a cell.

02:07 So option a that says process molecules to deliver them to the correct location in the cell is true.

02:13 Then we have option b that says convert energy into atp and this is false.

02:17 Okay, this is not a function of what the apparatus.

02:19 Option c says make plasma a membrane and this is false.

02:23 The plasma membrane is practically mainly or is mainly made of lipids...
