Answer:

C. It is active transport, and moves against the concentration gradient.

Explanation: Pinocytosis is an active transport in which the molecules move from a low to a more higher concentration gradient. During this process it requires energy to move molecules and the energy used is ATP.

Active transport requires the input of energy into a system so as to move solutes against their electrochemical and concentratio
gayaneshka [121]

Answer:

K+-coupled.

Explanation:

The transport of the solutes may occur along the concentration gradient or against the concentration gradient. Two main types of transport that occur in living organism are active process and passive process.

The passive transport do not require the energy for its transport whereas the active transport require energy. The K+ coupled transport do not require any energy molecule for its transport and easily transfer by the leaky channel. Hence, the K+-coupled transport is not the common active transport.

Thus, the correct answer is option (C).

Hatshy [7]

Answer:

Agree

Explanation:

The biotic factors of an ecosystem include all the populations in a habitat, such as all the species of plants, animals, and fungi, as well as all the micro-organisms. Also recall that the nonliving factors are called abiotic factors. Abiotic factors include temperature, water, soil, and air.

Steps in protein synthesis Step order : initiation complex formed with addition of large ribosomal subunit translocation small r
Alina [70]

Answer:

1. transcription of mRNA from DNA

2. small ribosomal subunit binds to mRNA

3.initiation complex formed with addition of large ribosomal subunit

4.codon recognition (non-initiating site)

5.peptide bond formation

6.translocation

7. ribosome reads a stop codon

8.polypeptide chain is released from the P site

9. ribosomal subunits dissociate

Explanation:

The translation is a process which translates the nitrogenous bases or codons in the proteins.

The process of translation requires the mRNA, tRNA and ribosome and proceeds in three stages: the initiation, elongation and the termination.

The process begins with the binding of the small subunit of the ribosome to the mRNA. The charged tRNA with a first amino acid called methionine binds the mRNA and scans the mRNA until it finds the start codon.  

After it finds the start codon, the large subunit complex binds the mRNA and form initiation complex. After this, the amino acid enters the P-site of the ribosome where elongation of peptide takes place.

The peptide then exits from the E-site and the ribosome dissociates.
