Expert Curated Digital Flashcards

MCAT Biology

There is a ton of bio on the new MCAT. Master it faster with Brainscape and Next Step Test Prep.


Whether you’ve been studying for months or are just starting to think about the MCAT, you’ll notice one thing: the new test contains SO much biology! From the difference between aldosterone and ADH to the trickiest genetics and Hardy-Weinberg practice, this subject will get you the content knowledge needed for a top score – faster than any other study method out there.

About Next Step Test Prep

The world's most complete & efficient MCAT Science Review app was made in partnership between Next Step Test Preparation and the learning scientists at Brainscape.

Since 2009, Next Step Test Preparation has helped thousands of students raise their scores on the MCAT. With a unique one-on-one tutoring program including full-length MCAT practice exams and books, Next Step is emerging as the foremost experts on medical school prep.

And while this MCAT app will be a terrific tool for whatever the overall MCAT prep approach you are using, it goes even better with Next Step's other MCAT services. Next Step has built a complete set of 5 full-length practice exams (along with our free-to-register half-length diagnostic) from the ground up for the 2015 exam. Integrating the revised exam's focus on biology and biochem and the new behavioral sciences section, these exams are the best possible preparation after official materials are exhausted. Students also turn to Next Step’s series of 9 prep books available on Amazon for hundreds of practice passages and thousands of practice review questions. To learn more:

Next Step's signature one-on-one tutoring program is a good fit for students looking for intensive, personalized preparation for the exam, with tutors selected through a rigorous hiring process that insures that you will work with a true MCAT expert. From first diagnostic to test day, Next Step works with you to deep-dive on problem areas and polish test-taking skills. To learn more:

# Deck Name Num. of Cards

Respiratory System And Tissues

Not only does the MCAT require a basic knowledge of respiratory function, but it also constantly relates it to other systems through concepts like the bicarbonate buffer, hemoglobin’s affinity for oxygen, and the immune role of the respiratory tract. Use these cards to master the respiratory system, as well as skin and other epithelial tissue types.


Muscle And Skeletal System

From the neuromuscular junction to the role of calcium in smooth muscle contraction, use these cards to master the muscular and skeletal systems as they appear on the MCAT.


Digestive System

From pepsin and trypsin to the role of lacteals, use these cards to master the digestive system as tested on the Biological & Biochemical Foundations section of the MCAT.


Kidney And Excretory System

Always a favorite of MCAT test-makers, the excretory system can also be a major source of confusion. Use these cards to master filtration, reabsorption, and secretion, as well as hormone involvement and the complexity of the loop of Henle.


Circulatory System

With the new MCAT’s increased focus on biology, understanding the circulatory system has become especially important. Use these cards to master MCAT favorites like the blood buffer and the Bohr effect, as they appear on the Biological & Biochemical Foundations section.



Having trouble remembering the difference between directional and disruptive natural selection? Can’t quite recall the definition of genetic drift? Use these cards to master evolution as tested on the Biological & Biochemical Foundations section of the MCAT.


Dna And Protein Synthesis

DNA, RNA, and protein synthesis is a major topic in both biology and biochemistry. With these cards, you can master the content knowledge required to attack a complicated question or understand a dense experiment-based passage.


Eukaryotic Cell

With the biological focus of the new MCAT, an understanding of eukaryotic cells is especially vital. Use these cards to familiarize yourself with microtubules and microfilaments, the phases of mitosis, and the various types of membrane transport. For enhanced practice, think about how these concepts relate to real-life topics like cancer and human aging.



What’s the difference between conjugation, transformation, and transduction? What does it mean when we say that prokaryotes are polycistronic? Master these topics and much more, and gain that confidence you need for the Biological & Biochemical Foundations section of the MCAT.


Nervous System

Topics like action potentials and the difference between sympathetic and parasympathetic activity are constant favorites of the MCAT test-makers. Use these cards to master these concepts as they are tested on the Biological & Biochemical Foundations section.


Endocrine System

The MCAT requires an in-depth understanding of hormones, from the difference between peptides and steroids to their effects on other organ systems. Use these cards to master endocrine organs, specific hormones, and the complex interactions involved.


Lymphatic And Immune Systems

Antibodies, antigens, macrophages, monocytes, neutrophils…the immune system is complicated, but understanding its components is essential for many MCAT questions and passages. This deck covers all of these topics, as well complex concepts like clonal selection and blood transfusions. Use these cards to master the lymphatic and immune systems as tested on the MCAT.



What’s the difference between pluripotent, totipotent, and multipotent? How can you relate a spermatogonium, a primary spermatocyte, and a spermatid? Use these cards to see how all of these topics connect, and you can master reproduction and development as tested on the MCAT.



Feeling a bit rusty with the Hardy-Weinberg equation? Having trouble remembering the difference between incomplete dominance and codominance? Use these cards to master Mendelian genetics as it appears on the Biological & Biochemical Foundations section.
