D is also true. Parathyroid hormone does activate D3 metabolism in the kidney.
PE

E is definitely true. Sunlight is crucial for D3 synthesis.
MA

I feel like C is misleading. Hydroxylation happens in the kidney, not the liver.
RI

Agreed, A seems off. The liver doesn't need Vitamin C for D3.
CH

D is correct, parathyroid hormone plays a big role!
TE

E is definitely true, sunlight is key for D3!

Wait, are you sure about C? I thought it was in the liver.
MO

Wait, there's a vitamin D3? I thought it was just called "the sunshine vitamin."
CI
Ciara

Haha, who needs vitamins when you can just sunbathe all day? Vitamin D3 is overrated anyway.
ET

E is the correct answer. Skin activates the synthesis of vitamin D3 by sunlight.
DE
Delmy

D is the correct answer. Parathyroid hormone activates the metabolism of vitamin D3 in the kidney.
HE
Herminia

C is the correct answer. Vitamin D3 is hydroxylated in the liver, not the kidney.
RE

I recall that the skin does synthesize vitamin D3 with sunlight, so E should be true. That leaves us with A or C as possible false statements.
CO

I practiced a question similar to this, and I think parathyroid hormone does play a role in activating vitamin D3 in the kidneys, so D seems correct.
JE
Jerilyn
9 months ago
I'm not entirely sure, but I feel like vitamin C's role in vitamin D3 metabolism is not really a thing, so A could be the answer.
MA
Markus

Hmm, I think D is the false statement here. Parathyroid hormone doesn't activate the metabolism of vitamin D3 in the kidney, it's the other way around - the kidney activates vitamin D3 metabolism.
GE

I'm a bit unsure about this one. I know vitamin D3 metabolism involves the liver and kidneys, but I'm not totally clear on the specifics. I'll have to review my notes before answering.
ST
Stephanie

I remember learning that the liver is involved in the hydroxylation of vitamin D3, so I think C is the correct answer. The other options seem like they might be false statements.
GR
Gracia

I think I remember that vitamin D3 is primarily hydroxylated in the liver first, so maybe option C is false?
PR
Princess

I think A is the false statement. Vitamin C doesn't help with D3 absorption.
CE
Cecil
10 months ago
Totally agree, D3 hydroxylation happens in the kidney!
MA
Marleen
10 months ago
No, C is actually true. Hydroxylation in the liver is a step, but not the main one.
DA
Daniel
10 months ago
A is false, vitamin C doesn't help with D3 absorption.
AL
Albert
11 months ago
Okay, I'm pretty sure the skin activates the synthesis of vitamin D3 by sunlight, so that rules out E. But the rest of these are a bit confusing.
DU
Dustin
11 months ago
Hmm, this seems like a tricky one. I'll need to really think through the metabolism of vitamin D3 to get this right.
AR
Aretha

E is definitely true, sunlight is key!
BE
Beth

But isn't D true?
MO
Mose

C seems incorrect too.
CO
Corinne

I agree, A sounds off.
LI
Lili

I think A is the false one.
