Question

please answer all :)

1. The direct movement of substrates from one enzyme to the next is called:

an electron acceptor.

substrate channeling.

a protein complex.

a cell with sufficient available water.

a linker coenzyme.

2. What is substrate-level phosphorylation?

phosphorylation of ATP coupled to an ion gradient

ATP synthesis when the phosphate donor is a substrate with a high phosphoryl-transfer potential

ATP and AMP synthesis from two molecules of ADP

phosphorylation of glycolytic intermediates that have a high phosphoryl-transfer potential

phosphorylation of AMP by ATP with 3-phosphoglycerate as a substrate

3. The anaplerotic reactions associated with the citric acid cycle are a result of

the use of many of the citric acid cycle intermediates in biosynthesis.

the oxidative nature of the citric acid cycle.

the decarboxylation reactions.

the production of GTP and reduced coenzymes.

4. Choose the CORRECT sequence of action of ATP translocase.

binding of ADP from the cytoplasm with the translocase → eversion of the transporter → releasing ADP into the matrix → binding of ATP from the matrix → back eversion to the primary confirmation of ATP translocase → releasing ATP into the cytoplasm

binding of ATP from the cytoplasm with the translocase → eversion of the transporter → binding of ADP from the matrix → back eversion to the primary confirmation of ATP translocase → releasing ADP into the cytoplasm

electrons enter the mitochondrial electron-transport chain → electrons transfer to ATP translocase → eversion of the transporter → proton transfer to the translocase → binding of ATP → releasing ATP into the cytoplasm

electrons enter the mitochondrial electron-transport chain → electrons transfer to ATP translocase → binding of ADP from the cytoplasm with the translocase → eversion of the transporter → binding of ATP from the matrix → releasing ATP into the cytoplasm

binding of ADP from the cytoplasm with ATP synthase → ADP transfer to the transporter → eversion of the transporter → releasing ADP into the matrix → binding of ATP from the matrix → back eversion to the primary confirmation of ATP translocase → releasing ATP into the cytoplasm
