Which statement is true for some photosynthesizing animals?

2 answers:

The correct option is A.
Scientists had discovered that some animals, such as Elysia chlorotica has the capacity to photosynthesize. The animal usually incorporate chloroplast into its cell from the algae which it feeds on. The chloroplast enable it to make proteins which are essential for photosynthesis.

The right answer is A. Some carry out photosynthesis...

The sea slug, Elysia chlorotica, is the first discovered animal able to use photosynthesis to produce energy. This photosynthesis is performed by the chloroplasts of its main food source, the seaweed Vaucheria litorea. They are sequestered by the digestive epithelium of the slug for several months according to a phenomenon of kleptoplasty, continuing their function of carrying out photosynthesis.

However, the chloroplasts of Vaucheria litorea have transferred a large part of their genes required for photosynthesis to the nucleus of the cells of this alga during evolution. Photosynthesis is nevertheless maintained in the sea slug thanks to the transfer of a gene necessary for photosynthesis from the kernel of the seaweed to the genotype of the slug.

How does the thickness of the Moon's mantle compare to the thickness of its core?

Vera_Pavlovna [14]

The mantle is the mostly-solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.

Which of the following experimental data would suggest the presence of a transmembrane protein? The primary sequence contains st

Zina [86]

Answer:

All of the other answer choices suggest the presence of a multipass transmembrane protein.

Explanation:

The primary sequence contains stretches of polar and nonpolar amino acids, suggesting an amphipathic design.

This one could be, because of the presence of polar an nonpolar aminoacids. The phospholipids membrane have the same construction.

The protein has windows of the primary sequence with positive hydropathy values separated by windows of the primary sequence with negative hydropathy values.

The same here, having pieces of positive and negative hidropathy can be a sign of transmembrane protein.

The protein isolates with the membrane fraction of the cell rather than the cytoplasmic fraction of the cell.

This is discribing you a transmembrane protein

During glycogenolysis, glycogen is broken down and converted to glucose-6-phosphate, which can enter glycolysis or be used by th

klasskru [66]

1. The enzyme glycogen phosphorylase removes terminal glucose residues from glycogen by cleavinα(1,4) linkages.

2. Enzyme activity stops when the enzyme reaches a point four glucose residues from a branch point, which is an α(1,6) linkage

3. The transferase activity of the debranching enzymes moves three glucose residues to another branch, connecting them by an α(1,4) linkage

4. The glucosidase activity of the debranching enzyme removes the glucose at its α(1,6) linkage

5. The enzyme glycogen phosphorylase continues removing terminal glucose residue

Explanation:

Several enzymes are required for the breakdown of a glycogen molecule to a glucose-6-phosphate molecule through glycogenolysis. These enzymes are completely responsible for degrading the glycogen, remodeling the glycogen and converting the glycogen. This is a regulatory process which takes place where is glucose lack or to accelerate fluid. The main enzymes that take part in this glycogen pathway are glycogen phosphorylase and the degrading enzyme.
