Physio

Hypotonic

A solution that has a lower concentration of solutes compared to another solution, causing cells to swell.

Chemo-receptor

A sensor in the circulatory system that detects changes in the chemical composition of blood.

Membrane fluidity experiment

The validation that the membrane was fluid was shown by the intermixing of labeled antibodies.

Primary active transport

A process in which a protein uses ATP to transport ions across a plasma membrane.

Hemolyze

When a red blood cell bursts due to being in a hypotonic solution.

Denature

A process where proteins lose their shape and function due to extreme conditions such as high temperature.

Integrator

A component in a homeostatic pathway that measures an incoming signal and sends a response.

Stages of mitosis

The correct order is prophase, metaphase, anaphase, telophase.

Proteins

Organic molecules made up of amino acids, not cellulose.

Disturbance in blood glucose homeostasis

A permanent decrease in insulin production from the Islets of Langerhans.

Total cholesterol level 300 mg/100 ml

Recommendation is to eat oatmeal and flax to increase HDL levels.

Unsaturated fatty acid

Formed by a dehydration synthesis reaction on a saturated fatty acid.

Antioxidants

Molecules that do not speed up reactions in the body.

Non-polar molecules

Molecules that do not dissolve in water.

Transport protein

Required for the movement of certain molecules across the plasma membrane.

Interphase

The phase of the cell cycle where the cell is functioning normally.

Cofactors

Molecules that activate enzymes, such as vitamins.

Complementary pairing of DNA nitrogenous bases

The correct pair is cytosine (C) and guanine (G).

Meiosis

A type of cell division that results in gametes with half the chromosome number.

Net water movement direction

Occurs from an area of lower solute concentration to an area of higher solute concentration.

Components of DNA

Not composed of ribose sugar.

Triglycerides

One of the three kinds of lipids along with phospholipids and steroids.

Dehydration synthesis

The chemical reaction that combines glycerol and fatty acids to form triglycerides.

Sodium Ion transport

Requires a transport protein to move through the plasma membrane.

Incorrect statement for meiosis

It does not result in a gamete that is diploid (2N).

Cytokinesis

Takes place during the telophase of the cell cycle.

Vitamin D

Produced by the body when exposed to sunlight, assists with calcium absorption.

Macromolecules for fuel order

Carbohydrates, lipids, proteins.

Cholesterol solubility

Cholesterol cannot dissolve in water/blood.

Cell membrane permeability

Cell membranes are not completely permeable to all substances.

Homeostasis

The stable internal condition maintained by living organisms.

Cholesterol function

Provides structural support for the plasma membrane.
