8-3 Mechanisms of Transport. For each of the following statements, answer with a D if the statement is true of simple diffusion,

with an F if it is true of facilitated diffusion, and with an A if it is true of active transport. Any, all, or none (N) of the choices may be appropriate for a given statement. (a) Requires the presence of an integral membrane protein (b) Solutes move down their free energy gradient in the direction of thermodynamic equilibrium (c) Is not subject to saturation (d) Requires the hydrolysis of ATP (e) Is a way of establishing a difference in the concentration gradient of solutes across a membrane (f) Applies only to small, nonpolar solutes (g) Applies only to ions (h) Transport can occur in either direction across the membrane, depending on the prevailing concentration gradient (i) Has a positive G (j) Usually has intrinsic directionality

Answer:

(a) Requires the presence of an integral membrane protein -F

(b) Solutes move down their free energy gradient in the direction of thermodynamic equilibrium - N

(c) Is not subject to saturation - N

(d) Requires the hydrolysis of

ATP - A except secondary active transport

(e) Is a way of establishing a difference in the concentration gradient of solutes across a membrane - D

(f) Applies only to small, nonpolar solutes - D

(g) Applies only to ions - A

(h) Transport can occur in either direction across the membrane, depending on the prevailing concentration gradient - D

(i) Has a positive G(Gradient) - D

(j) Usually has intrinsic directionality

Explanation:

Simple Diffusion is the movement of solutes from a region of higher concentration to a region of lower concentration through a semipermeable membrane.

When then is through a transmenbrane integral protein, it is a facilitated diffusion

Active transport uses chemicals (e.g ATP) to move ions against the concentration gradient (Lower to Higher concentration).

They are two types(Primary and Secondary Active transport). Secondary active transport do not require ATP

Normally, how many chromosomes are required to determine the outward expression of a trait?a homologous paironly oneany twotwo p
jeka94

Answer:

A homologous pair

Explanation:

In determining the expression trait of humans, this is based on the homologous chromosomes. This in turn comprised of alleles otherwise known as homologous alleles. The homologous loci are thereby located in these alleles which served as the formation of traits when combined.

Hence, normally, A HOMOLOGOUS PAIR is required to determine the outward expression of a trait?
