Huh?????????????? i’m confused
The steroids gain access to their receptors because steroid hormones are lipid soluble and can readily diffuse through the lipid bilayer of the cell membrane.
The steroid hormone dissociates from its plasma carrier protein and diffuses throughout the mobile membrane. After gaining entry to the mobile, the free hormone binds to an intracellular receptor and alters gene transcription.
In keeping with the free hormone speculation, due to their hydrophobicity, steroids are able to freely diffuse across lipid bilayers; but, megalin-established endocytosis has been proven to be at the least partly answerable for the uptake of sex hormones and nutrition D.
Steroid hormones, in general, are believed to freely diffuse across a membrane partly due to their close resemblance to ldl cholesterol, but recent evidence indicates that they could additionally enter cells thru receptor-mediated endocytosis.

Answer:
<u>a. the production of ATP</u>
<u />
Explanation:
Photosynthesis is type of biosynthesis that produces glucose from the reactants sunlight, carbon dioxide and water. It happens in two phases of the chloroplast, the light-dependent and light-independent reactions. In a light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths. Here,
- Light energy stimulates photosystem complexes formed from chlorophyll. Photosystem II then absorbs and transfers light to a reaction core.
- Water undergoes hydrolysis or splitting to yield an electron, a proton (H+) and oxygen.
- energy is passed along the electron transport chain, where it forms builds up H+ and an electrochemical gradient in the thylakoid space
- These protons pass through the ATPase enzyme embedded within the membrane, into the stroma, generating ATP from ADP.
- NADPH is generated from NADP+
