Which is a direct result of the digestion of complex carbohydrates?

1 answer:

5 0

Complex carbohydrates such as amylose, amylopectin, and glycogen are several sugar molecules linked with glycosidic bonds and the latter two exhibits branching. The digestion of complex carbohydrates start in the oral cavity where an enzyme salivary amylase from the salivary glands break down these complex carbohydrates into smaller fragments called dextrins or limit dextrins. Next part of the digestion is in the small intestine, particularly in the duodenum, when the dextrins react to another enzyme, the pancreatic amylase, secreted from the pancreas, where dextrins are further converted to monosaccharides and disaccharides. Monosaccharides can be readily absorbed in the intestines, but disaccharides are further broken down to monosaccharides by enzymes in the brush border of the intestines.

Chromists reproduction

Verdich [7]

The eukaryotic kingdom known known as Chromista is composed of single celled organisms among which of all the algae containing chlorophyll a and c. Most of the species belonging to this group are also photosynthetic.

Due to the vast number of species, some Chromistas have an asexual reproduction, whereas other reproduce sexually.

Asexual reproduction is achieved by the process of cellular division known as mitosis in which a parent cell divides into two identical daughter cells.

Sexual reproduction occurs through flagellated zoospores. Male gamets are produced by the antheridia, the male sex organ of algae, ferns, fungi etc. The haploid female gamets are produced through mitosis in oogonia. The joining of two gamets is called syngamy.

The Ras protein functions as a molecular switch that is set to its "on" state by other proteins that cause it to expel its bound

Darya [45]

Answer: Ras activity would be significantly slower in its response to extracellular signals.

Explanation:

• GTPase acts as a catalyst in converting RasGTP (active state) to RasGDP (inactive state)

• A mutant lacking the GTPase activating protein cannot activate GTPase so thee will nit be any functional GTPase

• if GTPase is not present then RasGTP may be expdessed for longer periods of time and there will be a lag until it eventually switches "off)

4. A single-celled organism that a student observed under a microscope is shown below.

Katyanochek1 [597]

Explanation:

D. The organism is eukaryotic because it has membrane-bound organelles.

Cells are the basic microscopic units of all organisms. There are two cell types, Prokaryotes and Eukaryotes.

Prokaryotic ( meaning pro: before and Karyon: for kernel/nut) describes organisms which don’t have a cell nucleus or other organelles surrounded by membranes. Eukaryotic (eu meaning true), are organisms with a cell nucleus and several other organelles surrounded by membranes. Example prokaryotes do not contain: nuclei , Golgi apparatus, chloroplasts, mitochondria

Both may contain a cell wall (seen in eukaryotic fungi and plant cells)

Arranged in a phospholipid bilayer, the membrane is semi-permeable; allowing entry into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.

Their structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins
