What are the membrane structures that function in active transport?
a)cytoskeleton filaments integral proteins
b)carbohydrates cholesterol peripheral proteins

b)carbohydrates cholesterol peripheral proteins

Explanation:

- Integral proteins: those that cross the membrane and appear on both sides of the phospholipid layer. Most of these proteins are glycoproteins, proteins that have several monosaccharides attached. The carbohydrate part of the molecule is always from each outside the cell

- Peripheral proteins: they are not spread across the bilayer but are attached to the internal or external surfaces of the bilayer and easily separated from it.

The nature of membrane proteins determines their function:

- Channels: integral proteins (usually glycoproteins) that act as pores through which certain substances can enter or leave the cell

- Conveyors: they are peripheral proteins that change shape to give way to certain products

- Receptors: These are integral proteins that recognize certain molecules to which they bind or attach. These proteins can identify a hormone, a neurotransmitter or a nutrient that is important for cellular function. The molecule that binds to the receptor is called ligand.

- Enzymes: they can be integral or peripheral and serve to catalyze reactions at the membrane surface

- Cytoleskeleton anchors: these are peripheral proteins that are found in the cytosol part of the membrane and are used to fix the cytoskeleton filaments.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
