Why do living things store energy in lipids? Why does lipid catabolism produce more ATP? Why does life use carbohydrates as signaling molecules, and proteins as enzymes? Why the basic structure of a cell membrane (bi-layer) is proteins and lipids?
How do enzymes help living things carry out chemical reactions? What are the digestive enzymes and what do they do? How do hormones help regulate digestion? How are enzymes involved in regulating energy metabolism? How does bile help in the digestion of fats?
“I’d like to see a rethinking of how we define reefs that are worth protecting.”— Andréa Grottoli“What mattered was the size of the corals’ energy reserves, especially stored lipids,” explains Grottoli. “When we starve, our bodies metabolize fat, and other living things do the sa...
Like all viruses, HIV treads the fine line that separates living things from nonliving things. Viruses lack the chemical machinery that human cells use to support life. So, HIV requires a host cell to stay alive and replicate. To reproduce, the virus creates new virus particles inside a host...
To do this experiment you'll need: Lesson Summary Additional Activities Discussion Questions: Question 1: What is starch? How do plants use starch? How does starch end up in our food? Question 2: Describe an experiment we can use to test whether a food contains starch. What results would ...
Biochemistry studies the chemical processes within and related to living organisms. It is a laboratory-based science that combines biology and chemistry, often focusing on the molecular level of life. Structure and function of enzymes in metabolic pathways Role of lipids in cell membrane structure and...
Plus, when you do weird things, you’re more likely to run into weird problems. For example, most foods have small amounts of nutrients that are bad to eat in large quantities. If you start eating 10x the normal amount, you can run into problems nobody would ever think to warn you ...
Biomolecules are substances that are produced by living organisms and that are essential for the cell survival. They are composed of small building blocks or monomers that are joined together to form polymers. The four main types of biological molecules are 1) carbohydrates, 2) lipids (fats),...
The cell membrane is a semi-permeable membrane meaning while it is a barrier against some biological molecules it will let things like waters and alcohols permeate through to the other side (and do so relatively quickly). It is composed of a phospholipid bilayer where the extrac...
Cardiolipins are a group of lipids found in heart muscles. What products would be formed if all ester bonds, including phosphates, were saponified by treatment with aqueous NaOH? Which of the following compound is a potential intercalator and mutagen? a....
