Which statement about the respiratory electron transport chain is true?
a. electrons are received from nadh only.
b. the terminal electron acceptor is usually h2o.
c. most of the respiratory proteins are in the cytosol.
d. energy must be added to move electrons from one electron carrier to the next.
e. electrons are passed from donor to recipient carrier molecules in a series of oxidation–reduction reactions.

Explanation:

Letter A is false, because electrons are received from NADH and FADH2

Letter B is false, because the terminal electron acceptor is usually O2

Letter C is false, because most of the enzymes are part of the inner mitochondrial membrane.

nonconformity

answer: the unkar group shows angular unconformity because the layers are turned at angle.

unconformity

answer: specifically the angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled. an angular unconformity occurs between the cambrian and precambrian rocks. the dox sandstone, shinumo quartzite, hakatar shale, and bass limestone have been filled.

disconformity

answer: the disconformities aremarked irregular lines between the sedimentaryrocks layers.
