Introduction to Metabolism

Choose the pair of terms that correctly completes this sentence: Catabolism is to anabolism as is to           .
a. exergonic; spontaneous
b. exergonic; endergonic
c. free energy; entropy
d. work; energy

They consume energy to build up polymers from monomers.

They release energy by breaking down polymers into monomers.

They increase the entropy of the organism.

Which of the following statements is TRUE regarding anabolic pathways?a) They are used for digesting sugars.b) They consume energy to build up polymers from monomers.c) They release energy by breaking down polymers into monomers.d) They increase the entropy of the organism.

Catabolic & Anabolic Pathways

The continuous removal of the products of a pathway to be used in other reactions

No. This is one possible way that a pathway can be displaced from equilibrium, but there is a better answer.

An input of free energy from outside the pathway

No. Although heat is a form of energy, it cannot be used by cells as an input of energy to change the DG of a pathway. A sufficient input of heat would likely damage the cell.

The first, second, and third listed responses are correct.

The first and second listed responses are correct.

What does equilibrium mean in terms of free energy (DG), and how can you make a system move away from equilibrium?

Metabolic pathways in cells are typically far from equilibrium. Which of the following processes tend(s) to keep these pathways away from equilibrium?

SCIENTIFIC THINKING Several studies have found a correlation between the activity levels of brown fat tissue in research participants following exposure to cold and their percentage of body fat. Devise a graph that would present the results from such a study, labeling the axes and drawing a line to show whether the results show a positive or negative correlation between the variables. Propose two hypotheses that could explain these results.

What is metabolism in biology?

Metabolism, Anabolism, & Catabolism - Anabolic vs Catabolic Reactions

An average adult human requires 2,200 kcal of energy per day. Suppose your diet provides an average of 2,300 kcal per day. How many hours per week would you have to walk to burn off the extra calories? Swim? Run? (See Figure 6.4.) <img class="fr-dib" src="https://lightcat-files.s3.amazonaws.com/problem_images/122d79d70f6894ad-1677715011672.jpg" style="width: 300px;">

Which of the following metabolic processes can occur without a net influx of energy from some other process?
a. ⓅADP+Ⓟi→ATP+H2O
b. C6H12O6+6 O2→6 CO2+6 H2O
c. 6 CO2+6 H2O→C6H12O6+6 O2
d. Amino acids → Protein

Metabolism Intro (2016) IB Biology

Which of the following terms specifically describes the metabolic process of breaking down large molecules?a) Catabolism.&nbsp;b) Metabolism.c) Anabolism.d) Dehydration.

Degradation of organic molecules by anabolic pathways provides the energy to drive catabolic pathways.

No. Catabolic pathways release energy derived from the breakdown of organic molecules; this energy is used by anabolic pathways.

Energy derived from catabolic pathways is used to drive the breakdown of organic molecules in anabolic pathways.

No. Energy derived from catabolic pathways is used to drive the synthesis of organic molecules in anabolic pathways.

Catabolic pathways produce usable cellular energy by synthesizing more complex organic molecules.

No. Catabolic pathways degrade organic molecules, with the release of energy that can be used to drive cellular processes, including anabolic pathways.

The flow of energy between catabolic and anabolic pathways is reversible.

No. Anabolic pathways do not produce energy that can be used by catabolic pathways.

Anabolic pathways synthesize more complex organic molecules using the energy derived from catabolic pathways.

Consider the flow of energy between anabolic and catabolic pathways.

Which of the following correctly states the relationship between anabolic and catabolic pathways?
