[Ca2+] within the endoplasmic reticulum (ER) is 10-3M. Cytosolic [Ca2+] is 10-7M. Lysosomes in mammalian cells have an internal
Pani-rosa [81]

Answer:

B. Ca2+ import into the ER because it has the steeper concentration gradient

Explanation:

ΔGt =  RT㏑(C₂/C₁)

where ΔGt is the free energy change for transport; R = 8.315 J/mol; T = 298 K; C₂/C₁ is ratio of concentrations inside and outside each organelle.

For Ca²⁺ import

ΔGt = 8.315 J/mol * 298 K * ㏑(10⁻³/10⁻⁷)

ΔGt= 3.42 kJ/mol

For H⁺ import

ΔGt = 8.315 J/mol * 298 K * ㏑ (10⁻⁴/10⁻⁷)

ΔGt = 2.73 kJ/mol

From the above values, ΔGt is greater for Ca²⁺ import because it has a steeper concentration gradient

When dissolved in water, koh behaves as an acid that forms k+ and oh- ions. a base that forms ko- and h+ ions. a base that forms
Serggg [28]

Answer:

A base that forms K⁺ and OH⁻ ions.

Explanation:

The KOH is an Arrhenius base.

A is <em>wrong</em>. A base does not form H⁺ ions.

B is <em>wrong</em>. A metal hydroxide forms K⁺ ions, not KO⁻ ions.

D is <em>wrong</em>. The metal forms K⁺ ions, KO⁻ ions.
