Midterm Review Transport, Immune, Photosynthesis, & Respiration

Active Transport

Low to High

ATP

Diffusion

High to Low

White blood cells engulf & make antibodies

Cell respiration

Mitochondria

uses O₂ & glucose to

make ATP, CO₂ & H₂O

Respiratory System

Gas exchange takes place in alveoli

Gas Exchange

O₂ in CO₂ out

Anaerobic Respiration

humans make lactic acid when not enough O_2

Photosynthesis

Multiple Choice

• 1

• 2

• 3

• 4

Multiple Choice

A substance is most likely to diffuse into a cell when

• it is a large organic food molecule such as protein or starch

• it is enclosed in an organelle such as a vacuole

• the concentration of the substance is greater outside the cell than inside

• the pH of the substance is greater than the pH of the cell

Multiple Choice

Doctors sometimes use a vaccine to prepare the body to defend itself against future infections. These vaccines most often contain

• antibodies

• antibiotics

• white blood cells

• weakened pathogens

Multiple Choice

This type of white blood cell ingests microbes. A function of another type of white blood cell is to

• prevent the loss of blood from a wound

• produce specialized molecules that mark invaders

• increase the number of red blood cells in the blood

• cause gene mutations that will increase immune responses

Multiple Choice
