All of the following statements describe kinesin-I EXCEPT__________.

Biology
1 answer:
adell [148]3 years ago
4 0

Answer: Option A

Explanation:

Kinesin -1 is the major anterograde motor which helps in the transportation along micro tubules. This is important for the proper transport of the mitochondria, Golgi derived vesicles,  endoplasmic reticulum tubulin, mRNA and intermediate filament sub units.

It moves along the micro tubules and for this task it gets energy from the adenosine triphosphate.

The heavy chain of KInesin 1 is made of globular head via short flexible neck and has a light chain as well which ends in the carboxy terminal.

Outline what has to occur in the body for a reflex and a voluntary action to occur.
enot [183]

Answer:

For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,

movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.

This molecule is a product of photosynthesis and is a major source of energy for plants and animals. This molecule is converted
pentagon [3]

Answer:

This question is asking to identify the molecule being described.

The molecule is GLUCOSE

Explanation:

Photosynthesis is the process by which green plants make their food using energy from sunlight. This food, which happens to be the product of the photosynthetic process is GLUCOSE molecule. Glucose is the source of energy during cellular respiration for plants and animals as it is broken down to synthesize ATP.

The process of cellular respiration, which is carried out by virtually all living organisms make use of the GLUCOSE MOLECULE. The energy stored in the glucose molecule is converted to ATP in the mitochondria.

Choose the true statement(s) that support(s) the endosymbiotic theory. To be marked correct, you'll need to select all true stat
horsena [70]

Answer:

a.Many mitochondrial genes resemble proteobacteria genes, while the genes in the chloroplast resemble genes found in some photosynthetic bacteria.

c.Mitochondria and chloroplasts both have their own circular DNA and 70S ribosomes that are similar to those found in bacteria.

d.Mitochondria and chloroplasts replicate by a process similar to mitosis.

Explanation:

Endosymbiotic theory states that mitochondria and chloroplast which are organelles of eukaryotic cells were once independently living micro-organisms but with due course of time eukaryotic cells engulfed them and they become an integral part of these eukaryotic cells.

The resemblance between mitochondrial genes with those of proteobacteria and chloroplast genes with photosynthetic bacteria strongly support endosymbiotic theory. Apart from this, the presence of their own DNA that too circular just like prokaryotic microbes and 70 S ribosomes also support this theory. Also just like prokaryotic cells, before cell division mitochondria and chloroplasts undergo replication by means of a process known as binary fission.

State one adaptation of nephron in the kidney of a desert mammal​
lidiya [134]

Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.

Explanation:

The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.
