Question

In cellular respiration, most ATP is produced DIRECTLY as a result of ________.

Select one:

a. the movement of hydrogen ions across the inner mitochondrial membrane

b. the citric acid cycle

c. fermentation

d. the electron transport chain

Kudzu, an Asian vine introduced to the United States in the 1930s as a means to control erosion, is referred to as "the plant that ate the South" because it grows so fast and overtakes most plant species in its path. A recent and unusual way that some people are using to control kudzu growth is to allow goats to graze their land and eat the kudzu, roots and all. This is considered by some to be the most environment-friendly way to eliminate this invasive vine. How can we best describe the goats in this situation?

Select one:

a. a threatened species

b. an invasive species

c. a biological control agent

d. an integrated pest management agent

What is the basis of Mendel's laws?

Select one:

a. the behavior of chromosomes during prophase I of meiosis only

b. the behavior of chromosomes during mitotic anaphase

c. the behavior of chromosomes during prophase I and prophase II of meiosis

d. the behavior of chromosomes during metaphase I and anaphase I of meiosis

Which part of cellular respiration produces the most NADH?

Select one:

a. electron transport chain

b. citric acid cycle

c. glycolysis

d. fermentation

Answer 1

QUESTION 1

In cellular respiration, most ATP is produced DIRECTLY as a result of the movement of hydrogen ions across the inner mitochondrial membrane

In this context, the hydrogen ions which are located at the matrix space will be able to pass though the ATP synthase to the inner mitochondrial membrane producing directly ATP

QUESTION 2

The correct answer is a biological control agent. In this case, the goat is able to control the proliferation of the vine acting as a biological control agent.

QUESTION 3

The correct answer is the behavior of chromosomes during metaphase I and anaphase I of meiosis

QUESTION 4

In this case, the correct answer is the citric acid cycle also called The Kreb's cycle where 3 NADH are produces per turn.
